England striker Daniel Sturridge is a major doubt for their friendly with Germany.
Sturridge was unable to complete a full training session on Monday, having been called up to the squad despite nursing a thigh injury.

However, Sturridge's possible absence for the visit of Germany throws up a familiar quandary for England coach Roy Hodgson, who has a paucity of attacking options.
With Danny Welbeck and Theo Walcott sidelined through injury, Rooney's partner against Germany is likely to be Jermain Defoe, Rickie Lambert or Jay Rodriguez...
Struggled through a timid 57-minute debut against Chile on Friday and is regarded as more of a support forward than a striker. Would benefit from a show of faith from Hodgson but is better suited to a wider role, which could be occupied by Southampton teammate Adam Lallana.

Filling in commendably for Andy Carroll, Lambert's style chimes with Hodgson's pragmatism and he needs to be tested against a genuinely good side. Has excelled against Scotland, Moldova and Ukraine to varying degrees.
Has hit nine goals in the seven cup games for Tottenham this season and his directness would suit Rooney and Andros Townsend. The downside is his sheer greed, whereas Lambert and Rodriguez are more selfless options.
