Arsène Wenger expects Chelsea to change their tactics for Saturday's game - because their approach against Barcelona was a "one-day" solution.
Roberto di Matteo's team will arrive at Emirates Stadium on a high after beating the Catalan giants 1-0 at Stamford Bridge in Wednesday's Champions League semi-final first leg.
Didier Drogba scored the winner but Chelsea spent most of the game on the back foot as Barcelona dominated possession and probed for openings. Fine defending - and the woodwork - kept them at bay and Wenger believes Chelsea will come out of their shells for the London derby.
"On the day Chelsea had a gameplan that worked a little bit," reflected Wenger. "Maybe they were lucky because they [Barcelona] hit the woodwork twice but I feel Chelsea played well with the system they wanted to play.
"They did remarkably well because the three central midfielders did well, the two wide players worked very hard and Gary Cahill and John Terry had a great game. The two of them blocked some shots from [Lionel] Messi and were remarkable sometimes. They had a great performance on the day with what they wanted to do. And Drogba did the rest.
"They won't play the same way on Saturday, even for Chelsea that was a one-day solution. Because when you play against Barcelona you know they will have 70 per cent of the ball. Chelsea will not have much choice to play differently [in the second leg] but they have a lot of experience in their side and they know how to be on the pitch."
Chelsea are not the only London side to enjoy success despite adopting a defensive approach to big games. Arsenal did likewise in the 2005 FA Cup final when Manchester United controlled much of the game before losing a penalty shoot-out after a 0-0 draw.
"We were lucky in that cup final," recalled Wenger. "Manchester United had more chances on the day than Barcelona had the other night. We weren't that happy because we wanted to play well. We didn't choose the tactics, we were forced into it [by injuries]."Copyright 2015 The Arsenal Football Club plc.
