Watford boss Javi Gracia says his tactical approach will remain flexible.

A change from last season to this campaign that involves playing two strikers rather than one has been a feature of the Golden Boys' success, but Gracia does not believe it is as simple as a numbers game.

He said: “I prefer not to say I like this formation or that formation - I am more interested in what shape will work best to win a game. Sometimes we press high and other times a mid-block is better.

“My goals don't change. Let's try to win the next game. We have played four games so far but now they are in the past.

“When the players come back from international duty I am sure they will have a great focus, and its important for our work for the Manchester United game."
