Should we be playing a weakened side at Astra?

Looks like it will be mainly WHU's reserves at Astra tonight. Not sure about Bilic leaving Noble and Cresswell back in London… Yes, the Arsenal game is a priority but it's also a match we traditionally get beaten in. It rather negates the last five games if we don't play our strongest side and what effect might it have on confidence to go out of the Europa League so early? Tomkins, Collins, Sakho and O'Brien are suspended, while Valencia, Carroll, Reid and Obiang are all injured. On a more positive note it looks like Jenkinson and Lanzini might get games. It's a big opportunity for squad players like Amalfitano, Jarvis and Maiga, who have to finally come good if we are to win tonight.
