But we knew it would be very tricky, it is a hard place to come. He was not involved in that at all.
But Wenger insisted that Iwobi had not been drinking at the party and certainly not taken drugs and claimed he did not know if it affected his performance. "You are not responsible for the behaviour of your neighbour".
Wenger admitted Iwobi's performance against Forest may have been affected.
The Frenchman criticised his team after the holders relinquished their grip on the trophy, with Wenger experiencing defeat at the third-round stage for the first time since taking charge of the north London club in 1996. "You do not want to lose good players, do you?" he said. "But that is what is requested from a top professional". Arsenal had to beat Man City in the semi's past year and Chelsea in the Final, so perhaps he thinks it would make more sense to actually go for the League Cup (which he has never won) and he only has to beat Chelsea over the two-legged semi final before facing Man City in the Final.
"The manager made a lot of changes, gave a lot of trust to players who haven't played a lot recently and I don't think anybody justified their selection today", the captain said. "It's unacceptable", Wenger told reporters.
Wenger, serving a touchline ban, was forced to watch powerless from the stands as Rob Holding conceded a penalty that teenager Ben Brereton converted in the 64th minute to stretch the home side's lead to 3-1.
It was still a side packed with worldwide players which took to the pitch at the City Ground but the Championship club came out on top in an action-packed tie.
Arsenal's last League Cup-winning campaign came in the pre-Wenger era in 1993, with the Frenchman's team losing in both his final appearances in 2007 and 2011.
