Gunners back on top

Arsenal returned to the Premier League summit on Thursday after Theo Walcott scored twice as Arsene Wenger's side came from behind to win 3-1 at West Ham United.
Arsenal spurned several first-half chances at Upton Park and they were punished early in the second period when Carlton Cole put the hosts in front after Wojciech Szczesny spilled a shot from Kevin Nolan.
However, Walcott struck twice in three minutes to turn the game around, squeezing a low shot past West Ham goalkeeper Adrian in the 68th minute and then heading home a cross from substitute Lukas Podolski.
Podolski was making his first appearance since August after a hamstring injury and he marked his comeback with a goal in the 79th minute, drilling home from Olivier Giroud's lay-off.
Victory sent Arsenal three points above former leaders Liverpool, who visited fourth-place Manchester City later on Thursday, while West Ham slumped to second-bottom.
Chelsea also leapfrogged Liverpool, moving up to second place by beating Swansea City 1-0 in one of the day's 10 traditional Boxing Day fixtures.
Everton's hopes of making further ground on the Champions League contenders were thwarted, however, as they crashed to a 1-0 defeat at home to bottom club Sunderland.
Manchester United doggedly overturned a two-goal deficit to win 3-2 against Hull City at the KC Stadium and register their fifth consecutive win in all competitions.
Early goals from James Chester and David Meyler gave Hull a 2-0 lead, only for Chris Smalling and Wayne Rooney to bring United level before half an hour had been played.
Rooney's goal, a sumptuous volley, was his 150th for the club in the top flight and he contributed to the winner in the 66th minute by pressuring Chester, a one-time United youth player, to put through his own goal.
Newcastle United closed to within two points of the Champions League places by coming from behind to overwhelm nine-man Stoke City 5-1 at St James' Park.
Tottenham Hotspur's new permanent head coach Tim Sherwood saw his side draw 1-1 at home to West Bromwich Albion, for whom Jonas Olsson cancelled out Christian Eriksen's 36th-minute free-kick.
Southampton ended a run of six games without victory by winning 3-0 at Cardiff City through a Jay Rodriguez brace and a Rickie Lambert strike.
