Michael Owen has been promised a starting spot for England next Saturday - but Steve McClaren maintains no risks will be taken with the striker.
Yet, even if the 27-year-old, who is now one of only four players to hit the 40-goal mark for England, does not make it on to the pitch in tomorrow's game against Everton, McClaren still expects him to report for national duty on Tuesday lunchtime.
And, if he proves his fitness ahead of next weekend's Euro 2008 Wembley date with Estonia, Owen will be in.
''If he is fit, he will play,'' said McClaren.
''Two or three weeks ago, it seemed impossible but the situation is Michael's operation went well, he has been training with his physio all week and is training with Newcastle today and tomorrow.
''They will assess him and it is up to them what they do with him.
''Hopefully he comes through and hopefully he plays on Sunday but even if he doesn't he will join us on Tuesday.''
Although Allardyce has stressed he wants Owen to feature for Newcastle before he should consider appearing in an England shirt, McClaren is eager to play down any club versus country conflict.
The two managers have spoken regularly this week and their relationship remains cordial.
''I spoke to Sam this morning,'' said McClaren, at his England press conference at Tall Trees in Yarm yesterday.
''The club versus country issue is something that is blown up quite a lot. I have a great relationship with Sam.
''Newcastle fans should not be worried. They should be delighted he has come back so quickly.
''We will take no risk with the player but it will be our decision whether to play him or not.''
Having been so cagey about his team selection for Estonia, especially in light of Frank Lampard's return, McClaren's decision to go public with his desire for Owen to play.
Owen has scored more international goals than the rest of England's seven-strong strikeforce put together and the fact Lampard is second top scorer in the squad with 13, emphasises how much McClaren will rely on his senior front-man.
It was Owen's two goals against Russia last month which helped put the Three Lions on course for Austria and Switzerland next summer and his strikes in the previous wins over Israel and Estonia helped end a long-running barren spell which placed a huge question mark over England's qualification hopes.
With Owen Hargreaves, David Beckham, Gary Neville and Michael Carrick all ruled out on fitness grounds, there were no major surprises in McClaren's 27-man squad.
Also included along with Middlesbrough's Stewart Downing was West Ham's Dean Ashton, who is finally set to put 14 months of misery behind him on the England front.
Ashton was part of McClaren's first squad as coach, for the friendly against Greece in August 2006. The 23-year-old's dreams of making his debut were shattered by a broken ankle suffered in training which has required two operations.
