Smalling and Rooney would have expected to make the trip following some excellent performances for Man United during the 2015/16 season but Rashford wouldn’t quite have foreseen his inclusion at the start of the campaign.
The 18-year-old was playing academy football last year but his rise to prominence has been swift and England boss Roy Hodgson has recognised his efforts. All three players will be raring to go ahead of England’s opening group stage fixture against Russia on Saturday:
Smalling has established himself as England’s first-choice centre-back in recent months and he will expect to line up alongside one of John Stones or Gary Cahill against Russia.
Rooney’s role in the team is unclear – he is England’s record goalscorer but he has featured more in midfield recently – while Rashford will be on the substitute’s bench barring injury to Daniel Sturridge, Harry Kane or Jamie Vardy.
New United boss Jose Mourinho will undoubtedly have an eye on his players as he finalises his plans for next season.
