Jose Mourinho's men suffered a shock 3-1 loss at Vicarage Road last season and can ill afford a repeat on Tuesday as runaway Premier League leaders Manchester City already boast an eight-point cushion. He has got them playing, scoring goals, winning games so they are doing well. Watford have picked up in the last couple of weeks after losing three games on the bounce, including a poor result at home to Stoke City in the process.
"Before the game we will talk a little bit with each other but once the match starts it is Watford against Manchester United - and I want to win".
United are without an away win in the league since September. They have a good coach. The Hornets lost three straight Premier League games between October 21 and November 5, but have beaten West Ham and Newcastle United in their last two without conceding.
Manchester United's hopes of catching neighbour Manchester City in the Premier League title race may well rest on whether it is able to overcome an in-form Watford side at Vicarage Road on Tuesday.
United have been tight defensively this season, however, with just six goals conceded in 13 matches proving the best record in the division. We are going to have drops like this, so you have to try to stay positive and bounce back. They will continue to miss the likes of Chalobah (knee), Kaboul (hamstring) and Cathcart (knee) in midweek.
Romelu Lukaku is also in contention to start having looked to be in trouble for a clash with Gaetan Bong, while Marcos Rojo could be rested if Eric Bailly and Phil Jones make a return to fitness.
"It's a good opportunity for me to stay a little bit more with him", said Silva.
Benitez does not expect to have any more players back from injury for the West Brom match, though Isaac Hayden is set to replace Mohamed Diame after serving his one-match ban for five bookings.
Man United have won 9 of their last 10 matches against Watford in all competitions.
Mourinho failed to get the better of Silva in their last two meetings, with his Hull side holding United to a goalless draw in the league at Old Trafford just a week after beating them 2-1 in the EFL Cup semi-finals in January - albeit a scoreline that did not prevent the Old Trafford giants from progressing.
"I think Watford have made progress".
