Arsène Wenger has hailed the work Roberto Di Matteo has done since taking over as Chelsea's interim head coach.

The Italian assumed control following the departure of Andre Villas Boas at the start of March and has since inspired an upturn in his team's results.

Chelsea beat Barcelona in their Champions League semi-final first leg on Wednesday night and Wenger believes it highlights how quickly Di Matteo has adapted to his new role.

"They defended well and took their chance. They did not have many but that is basically it," Wenger told Arsenal Player.

"[Di Matteo] has done well. 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]."

Despite their packed schedule, Wenger does not expect Chelsea to show any signs of exhaustion in Saturday's clash at Emirates Stadium.

"I don't believe that [they will be tired] at all," he said. "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."
