Di Matteo has guided the Blues to 10 victories in 13 games since taking the reigns in early March, leading them to an FA Cup final and into the semi-finals of the Champions League.
And Wenger, whose side host their London rivals at Emirates Stadium on Saturday lunchtime looking to bounce back from their surprise defeat by Wigan, has been impressed by Di Matteo’s short spell in charge.
“[Di Matteo] has done well.” Wenger told Arsenal Player. “I think he has adjusted well to the club and to the team. You judge him if he gets a longer period though, like any manager. He has done very well until now and he is competent.
“Let’s remember, sometimes when a guy comes in and knows the club it gives him an advantage to be quick [to adapt].”
Chelsea’s latest triumph under Di Matteo came in the 1-0 victory over Barcelona in the first leg of their Champions League semi-final clash at Stamford Bridge on Wednesday.
But despite the return leg set to take place on Tuesday and Wenger’s men having not played since Monday night, the Frenchman has warned his side not to expect the Blues to be fatigued.
“They defended well and took their chance,” he continued. “They did not have many but that is basically it.
“I don’t believe that [they will be tired] at all. You expect to be playing Chelsea at their best and you cannot expect them, with the players and numbers that they have, to be tired.”
