The former Wigan and Everton boss, who guided the Red Devils to the semi-finals at the World Cup in Russia last summer, believes it is hard to do Messi justice with words – but he himself is a big admirer.
“He (Messi) is a player you can really enjoy,” Martinez told Barcelona.com.
“When he is out on the field, and he’s at a level like the one he showed in England, that’s something everyone can appreciate.”
Messi has been in fine form this season, registering 11 goals in as many games.
Ernesto Valverde has admitted he was indecisive about making substitutions against Valencia while Barcelona were chasing a winner.
Lionel Messi had cancelled out Valencia’s second-minute goal with an equaliser 20 minutes later, but Barca couldn’t find another goal to take home all three points and end their winless run in La Liga, which now stands at four games.
Valverde waited until the 84th minute to make his first substitution, bringing on Ousmane Dembele for Philippe Coutinho, before making another switch just two minutes later when he replaced midfielder Arthur with Rafinha.
“I left the substitutions until the end because I wasn’t sure about which moves to make,” the Barca manager said.
Though they had plenty of time to find a winner, only to be kept out by their hosts’ resilient defensive display, Valverde was happy with his team’s efforts.
It was the third time in four league games that Barcelona came from behind to secure a draw.
“Apart from the game against Leganes (2-1 loss), we’ve had a response to every problem that’s come up,” the manager said.
