Sam Allardyce fears Kevin Nolan will try to engineer a move from Bolton because he has failed to break into the England set-up.
The 24-year-old midfielder has spoken of his frustration at again being overlooked at international level.
He watched from a distance as England went down to Spain in midweek in a friendly atOld Trafford.
Bolton manager Allardyce believes the club captain has a point.
He said: 'Kevin is our 'Mr Consistency'.
'He is captain of the club for that reason. He has performed particularly well for three seasons on the trot.
'Kevin has scored goals and managed to get the club into Europe for the first time.
'If that is not good enough to get you in England squad I don't know what is.
'Even though Steve McClaren can call on Owen Hargreaves, Steven Gerrard and Frank Lampard, Kevin deserves at least a place in the squad.'
Allardyce added: 'I just hope he does not start thinking he is at a small club and to get into the England squad he needs to be at a bigger one.
'It would be very dangerous for me and Bolton if that was the case.'
