Alex Oxlade-Chamberlain is now a major doubt to feature for England at the World Cup after injuring his knee in the 2-2 draw with Ecuador last night, with the midfielder likely to be ruled out for two weeks.

Roy Hodgson has some serious thinking to do. The England manager will have to decide whether to replace the injured Ox with one of his seven standby players.

Under Fifa’s rules, a replacement can be called-up until a day before a nation’s first match, which in this case means Hodgson will need to make a decision on whether to stick with Oxlade-Chamberlain for the duration of the tournament in the danger that he could miss the entire campaign in Brazil.

England's opening contest, against Italy in Manaus is in just nine days.

So who are these standby players? Some are in Miami training hard and some are 'aving it large on their holidays, and some are seemingly too devastated to do anything...

Oxlade-Chamberlain had also endured an injury-hit season with Arsenal. Knee ligament problems forced him to make just 20 appearances in all competitions.
