Zidane left Madrid at the conclusion of the 2017-18 season and has been linked with positions ever since, including a director role at Serie A giants Juventus.
His immensely successful spell with Los Blancos, which included three consecutive Champions League titles and a La Liga crown, has pegged the 46-year-old in the elite managerial bracket.
And Zidane has declared his intention of making a coaching return after enjoying a short break from the game.
Zidane told TVE: “Certainly I’ll be coaching again soon because it’s what I like doing and what I’ve done all my life.”
There have been reports in England that Zidane could be heading to the Premier League with Mourinho’s third-season struggles at Old Trafford seeing him linked the hotseat there.
The Portuguese boss is under immense pressure after an inconsistent opening to the season and if the wayward start continues deep into the campaign, United may look elsewhere with Zidane thought to be high on their list of candidates.
The Tottenham striker is considered irreplaceable by both club and country, leading to concerns over fatigue as he continues to shoulder a draining burden.
He played for 573 minutes at the World Cup this summer, picking up six goals and the Golden Boot along the way, and has started 61 matches in all competitions since the start of last season.
Defeat against Switzerland would see England lose four games in a row for the first time in their history but the non-competitive outing in Leicester represents a chance to hand the 25-year-old a well-earned breather.
As many as nine changes are expected from the side which started the 2-1 Nations League defeat by Spain, with Eric Dier confirmed to captain a team set to feature the likes of Jack Butland, Ruben Loftus-Cheek, Fabian Delph, James Tarkowski and Danny Welbeck.
“Harry falls in the category in which we have several players where we have to watch how much they play,” said the Three Lions boss.
“It was a short break with no pre-season and everybody was back earlier than I am sure everybody would have expected for club matches, although that is entirely understandable.
“We talked a bit after the World Cup about the demands of the modern player. Everybody has got to play a part in that but the clubs own the player and they have got to do the right thing for themselves.
“Normally we have not got opposing objectives and the clubs would be holding their breath and hiding behind their sofas watching our teams go out.
“But this is one of those occasions where what we want to look at with our squad ties in with doing the right thing with the players for our long-term benefit. So I thought this is a good opportunity to do it.”
For Southgate, it is important for England to find a way of winning without their totemic centre-forward.
He has scored 14 goals in 14 appearances under Southgate – the kind of output that simply cannot be guaranteed elsewhere, particularly after Jamie Vardy’s decision to step away from international duty.
“There aren’t many English strikers playing,” admitted the 48-year-old.
“There’s obviously some older ones who have good goalscoring records at club level but I’m not sure that’s necessarily the route we want to go down. We’re hopeful that a couple of the younger ones will start to get games and develop.
“I still have a lot of faith in the likes of (Liverpool’s Dominic) Solanke in particular, who I think has been outstanding at every age level. But I can’t rule out anybody because if people play well it would be foolish to ignore them.”
The former Middlesbrough boss even hinted an ill-timed injury or two at the business end of the qualification cycle could see him testing Vardy’s suggestion he would return in dire circumstances.
“Not over the next few months…but if we get to the European Championship qualifiers and we think there’s a situation where we feel Jamie would come in and play then it might be different,” he said.
“But in this period, we’re determined to invest in some of those younger guys really.”
Southgate has been clear in the past about his concerns about the number of elite players at his disposal, and particularly the amount of game-time being experienced by those.
He did, though, balance that with a nod of sympathy towards his home nations counterparts.
“In fairness, if I was (Wales manager) Ryan Giggs or (Northern Ireland’s) Michael O’Neill, I’d be saying ‘what the hell is he complaining about?’ They have to select their players from different sources,” said Southgate.
“But we’re in a different era in terms of numbers of players who are in the pool.
“To be as good as we want to be going forward, it’s got to be some of the kids who have been successful at youth level for us. That’s a better investment for us in the long term really.”
Eriksen made it 15 goals in his last 18 international appearances with a double in Denmark’s 2-0 Nations League win against Wales in Aarhus on Sunday.
But the 26-year-old has not scored in his last 10 Tottenham games, his last goal coming in a 3-1 Premier League home defeat to Manchester City in April.
“It’s great to have that form, going into the weekend,” he said ahead of Spurs’ top-flight match against Liverpool on Saturday.
“I’ve always had many shots, even in the Premier League, but I just haven’t scored yet,” Eriksen said.
“I’m trying to get in good positions in every game to create something or take a shot, but they just keep flying in for the national team.
“Penalties are easy if you score, but in open play we create chances as well.”
Denmark manager Age Hareide said after the Wales win that Eriksen has a different role for the national team to the one he plays at Spurs.
The Danish plan is to get the ball quicker to him in more advanced parts of the pitch.
“I’m a little bit further up the pitch here and not so much involved in the build-up because we probably have less of a build-up than we do at Spurs,” Eriksen said.
“It’s a bit different with Denmark, we go for the long ball a bit earlier and try to get the second ball.
“Everyone wants to play like Spurs. We want to play attractive football, get the ball forward and create chances with good possession.
“My form with Denmark hasn’t been too bad, I got off to a very slow start with five goals in my first 50 games.
“It took me a while but I’m finally here. It’s almost going too well but I hope it carries on.”

Denmark went in to their Nations League opener after a turbulent week which had embarrassed the whole of Danish football.
A dispute over the players’ commercial rights saw Denmark field a side of lower-league and futsal players in the 3-0 midweek friendly defeat to Slovakia.
The row was only resolved late on Thursday after the players had left Denmark and returned to their clubs.
“It’s been a bit different this week flying back and forth but we handled it like professionals,” Eriksen said.
“The team didn’t show any negativity on the pitch, we stood together which is a good thing.
“It was a temporary deal and I hope most of it will be sorted and I hope we aren’t in the same situation next month.
“The Danish FA and Players’ Association will do their thing to get it sorted because it literally cannot happen again.
“The headline has been that we’re just playing for money, but there are a lot of details going on.
“For us it’s not about the money, it’s always an honour to play for your country no matter what and we have to solve this situation.”
