Arsenal captain Gilberto admits next week's game with Porto will likely prove to be the defining moment of their season.
Thierry Henry's reported but since denied spat with his manager Arsene Wenger has occupied plenty of column inches this weekend, but it is on the field where Arsenal will really be put to the test.
Arsenal are top of UEFA Champions League Group G but travel to Portugal, without Henry, in the knowledge that a defeat could end their European ambitions for another season.
Gilberto has called on his team-mates to put on a professional display against Porto, urging for absolute focus ahead of what will be tense affair in Portugal.
"This week will be very decisive for our future in the league and the Champions League," the Brazil midfielder said.
"We did our job but need to continue, on Wednesday we have a very difficult game against Porto away to decide our future in the Champions League.
"But we go there to come back with the result."
In Henry's absence at the weekend, Emmanuel Adebayor stepped into the Frenchman's illustrious boots and impressed in scoring against North London rivals Tottenham Hotspur in a 3-0 victory.
Whilst it is Henry that is making the headlines, Adebayor admits all Arsenal's players are frustrated with the lack of consistency they are showing, both domestically and abroad.
"It's easy to understand him because as a player, even me, I'm not happy with the way things are going - we lose one game, we win one game, we lose two games and draw one game," Adebayor added.
"It's not only difficult for Thierry, it's difficult for everyone - the boss, for us players, the chairman. We are passing through a difficult moment."
