Watford boss Marco Silva admits he knows little about Molla Wague.

Wague joined Watford on deadline day from Udinese.

Silva admits he couldn't consider selecting Wague for victory over Southampton.

"We give time to him. He's one player that I'm clear – I don't know very well. I analysed some games, but not enough. I need to give time to him and it's impossible for the next match."
