Arsene Wenger said a tactical change made the all-important difference for Arsenal in their Carabao Cup semi-final triumph against Chelsea.
Arsenal came from behind to win 2-1 at the Emirates Stadium, where Gunners boss Wenger switched to a back three – a change which caused the visitors problems straightaway.
Asked why he had made the change, Wenger said: “Because we (Chelsea and Arsenal) know each other well and had many draws. To win a game you have to score and I changed some things at half-time that worked well.”
Wenger insisted his side deserved to win despite the fortuitous nature of both their goals.
After Eden Hazard’s opener, Arsenal equalised courtesy of an own goal by Antonio Rudiger and another deflection off the German led to Granit Xhaka scoring the winner.
Wenger said: “In the first half there were psychological and tactical reasons for not expressing our game.
“We rectified it for the second half, won the ball high up and then controlled the game and we always looked like we could win this game.
“It was a deflected goal for the first and the second as well, but overall we controlled the game in the second half.”
