One Arsenal player has come in for a lot of criticism after Chelsea defeat

Roy Keane told us.

"Listen, he's had a good week," Keane said about a certain Arsenal forward.

"The guy needs to relax. Try to play well for the next seven or eight months."

Chris Sutton also told us. "People are saying he is a changed player," Sutton said.

"He is neither clever nor creative and he was completely ineffective once again for England."

The two were talking about, of course Theo Walcott. And they were both right. The Arsenal forward showed on Saturday that it was laughable that some thought a few months ago that he had finally developed into a good player. Walcott was abject as Arsenal lost 3-1 to Chelsea. In fairness, the whole Arsenal team was poor, but the 27-year-old was noticeably awful. He was at fault for Chelsea's opener. Here's Walcott's position as Marcos Alonso, the player he was meant to mark and the scorer of Chelsea's first goal, makes his way into penalty area. Walcott is still seemingly unaware of Alonso's presence as Diego Costa's header hits the crossbar. But he's at least he has got closer to him, so maybe he'll stay with him Or maybe not. But if another Chelsea player comes into play down the left Walcott will be be in a perfect position to stand near him looking useless. He finally looks towards Alonso... But, by then, Alonso, the player he was due to mark and was standing beside seconds earlier, has scored... This isn't a rookie on his debut in a top of the table Premier League clash. Walcott is the longest serving player in Arsenal's squad. He joined them 11 years ago and still plays like a sprinter who wandered into a football match. It may seem harsh to focus on Walcott after Arsenal were so poor, and saw their so-called title challenge end for another season. But Walcott Arsenal. Both are hyped before inevitably disappointing. Both lack any tactical nous. Both play well against weaker teams, but fail to convince in the big games. Saying Walcott will be a top player is like saying Arsenal will win the Premier League. It won't happen. Walcott represents this Arsenal team. There's absolutely no way he would have survived in a team with genuine ability to win the Premier League. His day didn't get much better after his role in Alonso's goal. According to football statistics website , Walcott was Arsenal's worst outfield player, (Hector Bellerin received a lower rating, but he was only on the field for 17 minutes). Walcott was substituted in the 70th minute, and at least broke a record, of sorts. He is now the first player to be substituted off 100 times in the Premier League. He received a lot of criticism on social media for his performance. https://twitter.com/OliPriceBates/status/827886107325038592 https://twitter.com/Grooganaldo/status/827879324091039745 https://twitter.com/Marly_D13/status/827898465774624769 https://twitter.com/Giroudesquee/status/827897407484620801 https://twitter.com/BarstoolSam/status/827860925352988673 https://twitter.com/danielstorey85/status/827860790527012864 https://twitter.com/henrywinter/status/827863420166926336 https://twitter.com/_Asgardian/status/827846211814227968 https://twitter.com/MarkOgden_/status/827860491821256704
