Arsenal boss Arsene Wenger has been impressed by the work of Watford rival Marco Silva.

The Gunners meet Watford on Saturday.

Wenger said: "He has impressed, because I think Watford play good football. He was at Hull where he had a very good start as well and overall I think he has done very well.

"They are a strong side. They have strong results, they're a balanced team who are dangerous and play good football. They're tough opponents for everybody."
