Manchester United goalkeeper Ben Amos is in line for a shock Premiership debut this weekend against Bolton Wanderers.

Sir Alex Ferguson concerned over the fitness of his three first-team goalkeepers ahead of the match against Bolton.

Edwin Van der Sar (knee) and Thomas Kuszczak (thigh) are doubts while Ben Foster is definitely out with an ankle problem.

Amos played in United's midweek League Cup win over Middlesbrough.

He has worked his way through the Old Trafford ranks since the age of 11.
