Arsenal 3-1 Bournemouth: Alexis brace and Walcott goal get Gunners back to winning ways

Alexis Sanchez continued his fine run of form by scoring twice in Arsenal's hard-fought 3-1 over a resilient Bournemouth at the Emirates Stadium on Sunday.
With Premier League leaders Chelsea, Manchester City and Liverpool all winning on Saturday the onus was on the Gunners to respond on home turf.
Arsene Wenger's men did not have it all their own way, though, as
Bournemouth - devoid of Arsenal-loanee Jack Wilshere - put in a good showing in north London.
It was a mistake of their own doing that saw Arsenal take the lead when Sanchez pounced on Steve Cook's error to break the deadlock, but Bournemouth's efforts were rewarded before half-time when Callum Wilson levelled from the penalty spot.
Arsenal produced a marked improvement after the break and afforded Bournemouth significantly fewer opportunities and they edged ahead early in the second half thanks to Theo Walcott's header.
Bournemouth continued to cause problems and were adamant that they should have been awarded a second spot-kick late on as they desperately sought a leveller, but Sanchez broke the visitors' resolve for good in injury time with his seventh goal in his past eight games.
Arsenal stay fourth as a result of the victory, three points adrift of table-toppers Chelsea.
Bournemouth gave a good account of themselves during the opening exchanges, but they shot themselves in the foot in the 12th minute.
Cook's horrendous back pass went straight to Sanchez and the forward stroked his effort past the stranded Adam Federici from 18 yards.
