England boss Roy Hodgson is facing a tricky decision over whether to include Manchester United forward Wayne Rooney in his squad to play Scotland at Wembley next Wednesday.
The 27-year-old has long been a regular in England's starting line-up but he has yet to get any game-time under his belt this pre-season, due to hamstring and shoulder problems.
And United say Rooney, who is rumoured to be seeking a move away from Old Trafford, may not be fit for Rio Ferdinand's testimonial on Friday and could even miss the Community Shield on Sunday.
The England squad will be named at 2pm on Thursday and, if selected, Rooney may link up with the national squad having not played in a match since last season.
He may well be required though because West Ham striker Andy Carroll (heel) is out until September, Tottenham's Jermain Defoe has a hamstring issue, and Liverpool's Daniel Sturridge is only just back in training.
Manchester United's new forward Wilfried Zaha came off the bench to make his England debut last November and he appears to be in line for a second call-up.
Danny Welbeck is the only regular England striker who is fully fit but his Manchester United team mate Ashley Young could be pushed forward, as could either Alex Oxlade-Chamberlain or his fellow Arsenal forward Theo Walcott.
Captain Steven Gerrard will return after missing three of the last four games and the Liverpool man could be joined in the starting midfield by Arsenal youngster Jack Wilshere but Chelsea's Frank Lampard may miss out with an Achilles injury.
Goalkeeper John Ruddy has been beset by a thigh injury since missing Euro 2012 with a broken finger but has been playing in Norwich's pre-season games and could be recalled.
The match against their oldest rivals in international football will be England's last before the crucial World Cup qualifiers against Moldova and Ukraine next month.
