Chelsea manager Jose Mourinho has revealed that he has a back-up plan if his pursuit of Manchester United striker Wayne Rooney fails.
Earlier in the summer Mourinho claimed Rooney was his only transfer target, and the Blues have since had two bids rejected for the 27-year-old.
The news represents a further blow to manager Arsene Wenger, who has already lost skipper Thomas Vermaelen (back), vice-captain Mikel Arteta (thigh) and Abou Diaby (knee) to lengthy absences.
Oxlade-Chamberlain was carried off at Emirates Stadium last Saturday following a collision with Aston Villa’s Antonio Luna during the 3-1 defeat.
Wenger admitted afterwards that it looked to be a “bad injury” but the extent of the damage could not be fully assessed until the swelling on the midfielder’s knee had diminished.
It is a shattering blow for Oxlade-Chamberlain, who had got the nod over Lukas Podolski to start for Arsenal last weekend and had been earmarked for more playing time this season, his third at the club.
It is also a setback for England manager Roy Hodgson, who would have been expected to select the 20-year-old for the crucial World Cup qualifiers in September and October.
Wenger has been forced to step up his efforts in the transfer m arket following the injuries to Arteta and Oxlade-Chamberlain, and on the back of a summer in which he has failed to make a single senior signing.
Arsenal had a £10m bid rejected by Newcastle for Yohan Cabaye on Monday, and as revealed by Goal, also enquired about Sevilla midfielder Geoffrey Kondogbia and made a £6m bid for Schalke right-back Atsuto Uchida.
Wenger is also weighing up whether to offer a one-year contract to Mathieu Flamini, who is training with Arsenal after being released by AC Milan at the end of last season.
