Arsenal face a test of their Premier League title credentials when they visit injury-hit Manchester United on Sunday afternoon.
United have experienced a disappointing campaign so far this season and currently lays in fifth place in the Premier League. Red Devils boss Louis van Gaal has been heavy criticised for the teams style of play, but of late his team have been massively injury-hit.
United have lost ground on the Champions League spots after failure to win their last two games in the Premier League with a draw against Chelsea and then a defeat against Sunderland last time out.
However they bounced back to winning ways in fine style on Thursday night, as they hammered Danish champions Midtjylland 5-1 at Old Trafford, with teenage debutant Marcus Rashford the unlikely hero grabbing a brace.
United will be hoping the win will resurrect their ailing campaign and would put them within three points of arch-rivals Manchester City who are fourth in the table.
The Red Devils will take heart from the fact that Arsenal have won just once in their last 12 visits to Old Trafford in all competitions.
Arsenal could head into this game five points behind Leicester, who play Norwich on Saturday, so a victory is vital to keep pace with the Foxes.
The Gunners suffered a 2-0 home defeat against Barcelona in the last-16 of the Champions League time out, but their league form of late has saw them record to wins and a draw from their last three games.
Their last Premier League outing saw the Gunners record a vital 2-1 win over title rivals Leicester at the Emirates Stadium, with substitute Danny Welbeck scoring a dramatic stoppage-time win.
Arsenal do not have a great recent record against United, as they have won just two of the last ten meetings between the two sides in all competitions, although those two victories have come in the last three meetings.
The Gunners have won at Old Trafford just three times in 23 visits in the Premier League and it is fair to say it is a bit of a bogey ground for the club from north London.
United have a major injury list heading into this clash. Luke Shaw, Wayne Rooney, Antonio Valencia, Ashley Young, Bastian Schweinsteiger and Marouane Fellaini are expected to miss out.
However, the Red Devils also have major doubts over the fitness of David de Gea, Anthony Martial, Matteo Darmian, Cameron Borthwick-Jackson and Chris Smalling.
Arsenal are without the usual suspects of Jack Wilshere, Santi Cazorla and Tomas Rosicky. Brazilian centre-back Gabriel is a doubt and midfielder Alex Oxlade-Chamberlain has been ruled with a knee injury picked-up against Barcelona.
Arsenal are favourites for this game at odds of 7/5, while Manchester United are odds of 9/4 and the draw is odds of 23/10.
The Gunners have a poor record at Old Trafford, but have avoided defeat on their last two visits and with United so plagued with injuries should have enough to win this clash.
