Poland international Moder and Belgium star Trossard have impressed for club and country of late. Moder was excellent on his first Premier League start during Albion's 3-0 win against Newcastle and followed that with a fine goal for his country against England at Wembley Stadium on Wednesday night.
Trossard has scored in his previous two matches for Brighton against Southampton and Newcastle and also netted his first goal for his country during the international break with sublime long range strike against Belarus.

1. Robert Sanchez
Impressed since he took over the gloves from Maty Ryan and will look forward to another stern this Sunday against Man United at Old Trafford. Called up to the Spain squad last week.
2. Joel Veltman
What a signing he has been. The Dutch international continues to impress following his 900k arrival from Ajax. Rarely puts a foot wrong and will need to be at best once more against United
3. Ben White
The Brighton defender will enjoy the challenge of pitting his wits up against Rashford, Fernandes and co.
4. Lewis Dunk
Quite simply Brighton's best player this season. Was part of a Brighton defence that was run ragged during a 3-1 loss last season Old Trafford and the skipper will be keen to put that right on Sunday
