Arsene Wenger could find himself in further disciplinary trouble with UEFA after communicating with the Arsenal bench during Tuesday night's 1-0 Champions League play-off first-leg win over Udinese at the Emirates Stadium.
The Frenchman received a one-match touchline ban for abusing Swiss referee Massimo Busacca in the last-16 defeat to Barcelona last season. Wenger's post-match criticism saw him banished to the stands for Tuesday evening's match, although he could find himself in further trouble for communicating with the bench.
Arsenal checked with UEFA that Wenger could send messages to the coaching staff via a third party. As a result, first-team coach Boro Primorac passed instructions from Wenger to assistant manager Pat Rice. However, UEFA warned Wenger at the break he was contravening the rules and as a result he withdrew from communication.
After the match, the Gunners boss felt that as he had not been involved in the match in the usual way he would not attend the post-match press conference.
Wenger will have been frustrated by the way his team were unable to go on to dominate the tie after taking an early lead through Theo Walcott.
But goalscorer Walcott is happy with the narrow lead heading into next week's second leg and is keen to move on from the sale of Cesc Fabregas who moved to Barcelona on Monday.
"We've just got to carry on," he said. "It's time to move on. He was a great player for the club but he's gone.
"We still have some very talented players in the squad here and we believe we can achieve something this year.
"We're in a great position but it's far from over. We didn't finish it off.
"But we dug in and gave absolutely everything. That's two clean sheets in a row now, and we're capable of winning over there."
