Arsenal captain Cesc Fabregas is 'optimistic' over his chances of facing Barcelona on Tuesday.
The Gunners travel to Camp Nou defending a 2-1 lead as the pair meet in the second leg of their UEFA Champions League second-round tie.
Spain international Fabregas has not played since withdrawing with a hamstring problem during Arsenal's 1-0 win over Stoke last month.
The 23-year-old will sit out the meeting with Sunderland at the Emirates on Saturday, but he is hopeful he will be on the plane bound for Barcelona.
"As far as my injury is concerned, I am feeling really good at the moment," said Fabregas, who missed Arsenal's Carling Cup final defeat to Birmingham last weekend.
"I am doing everything I possibly can to get ready as soon as I can.
"Physically I feel good and it was good to have a bit of a rest too because I am sure I will come back stronger.
"It may have even been possible for me to be on the bench for today's game, but we decided together that it would be better for me to rest well instead, have a good training session on Sunday, take a look Monday and then hopefully fly to Barcelona.
"I am optimistic that everything should be okay for Tuesday."
Arsenal, however, will definitely be without Holland striker Robin van Persie and England forward Theo Walcott for the mouth-watering European clash.
