Diego Simeone is already among the longest-serving managers at a single club in Europe's top five leagues, and his stay at Atletico Madrid is set to go on for longer.
The Argentinian's contract was due to expire at the end of this season, but he has now signed a two-year extension that will keep him at the club until the summer of 2020.
Simeone has been Atletico manager since 2011, leading the club to a Copa del Rey triumph and the league title in the 2013-14 season, while also taking Atletico to the Champions League final twice in three seasons.
He is the longest-serving manager in La Liga among current contingent, as he nears six years in charge at the Madrid club. That places him at fourth among the longest-serving current managers in Europe's top five leagues.
Arsene Wenger is the obvious name who tops this list - have a look at the gallery above to see the rest of the top ten.
