LONDON, ENGLAND - APRIL 05: Theo Walcott of Arsenal runs with the ball during the Premier League match between Arsenal and West Ham United at Emirates Stadium on April 5, 2017 in London, England.
Mesut Ozil, Theo Walcott and Olivier Giroud all found the net after the break to hand the Gunners a 3-0 Premier League success, West Ham's fifth defeat on the bounce.
The 29-year-old East London born Noble has really struggled this season, and his individual performances have exemplified West Ham's struggles as a whole, with Bilic's side now languishing in 15th in the Premier League table, just five points clear of the relegation zone.
"I feel that he's back physically with focus", the Arsenal boss said. He was hit hard by us going out in Champions League.
"As for myself, I think I've done okay since I came in, but we've still lost both games".
That individual does not attach the same significance as Wenger to a top-four finish but the Frenchman continued to argue his corner. We have been in this situation before, although probably not as bad. We are always praised maybe more than we deserve it when it goes well, and punished more than we deserve it when it doesn't go well.
He said: "You could see it was slowly starting to come".
Although Ozil grabbed the headlines with his 10th goal in all competitions and an assist, Xhaka produced arguably his best performance in an Arsenal shirt since arriving from Borussia Monchengladbach last summer.
While Giroud didn't smile, his manager couldn't hide his relief at picking up three points - especially as many fans could be heard singing "One Arsene Wenger" in the second-half. "It's not being negative, it is being realistic".
"To get that confidence back is the key point".
Gabriel did reasonably well during the second half and I expect the Brazilian will partner Shkodran Mustafi tomorrow night with Hector Bellerin and Nacho Monreal retaining their places at full-back.
Nonetheless, they'll be confident of getting back to winning ways against a free-falling West Ham, who sustained a fourth successive loss on Saturday by going down 2-1 at Hull. They started to play with much more freedom.
