Football - Lambert keeps close eye on duo

Aston Villa manager Paul Lambert will monitor the fitness of Christian Benteke and Ron Vlaar ahead of the New Year's Day trip to Sunderland.

Striker Benteke has missed the last three games with a knee problem, while defender Vlaar is on his way back from a calf injury.

Ciaran Clark is suspended, while the game is likely to come too soon for Joe Bennett as he recovers from his back injury.
