Alex Oxlade-Chamberlain will miss Arsenal’s trip to Manchester United after breaking down with a fresh injury in training, Goal.com can reveal.

The 19-year-old had recovered from a hip injury sustained at Norwich City 13 days ago and had been earmarked to make only his ninth Premier League start on the right flank at Old Trafford.

But Oxlade-Chamberlain did not travel with the squad to Manchester on Friday afternoon after picking up a groin injury in training.

The new setback is expected to keep the teenager on the sidelines for a further two weeks, ruling him out of Tuesday’s crunch Champions League visit to Schalke.

Aaron Ramsey is expected to replace Oxlade-Chamberlain on the right side of midfield despite the availability of Theo Walcott.

The midweek hat-trick hero is set to be on the substitute’s bench once again after playing all 120 minutes of the remarkable 7-5 Capital One Cup win over Reading.

Walcott has not started a Premier League match since contract talks with the club collapsed at the end of August.

Meanwhile, Jack Wilshere is poised to start a second consecutive league match after showing no ill effects from his first Arsenal match in 17 months against QPR last weekend. He will be joined in central midfield by Mikel Arteta and Santi Cazorla.

Vito Mannone will continue in goal even though No.1 Wojciech Szczesny, who has been sidelined for six weeks with an ankle injury, returned to full training on Monday.

Despite conceding a creditable 11 goals in 10 matches this season, Mannone has been guilty of a number of high-profile blunders, most recently when he gifted Norwich City the winner 13 days ago.
