SkySports pundit Paul Merson is confident weekend opponents Manchester United and Arsenal will both record wins in midweek.
Louis van Gaal's side are full of confidence after the win, but will have to be cautious against a team they needed a fortunate last minute winner to beat earlier in the campaign.
Merson predicts a 2-1 win for United, telling SkySports: "Man Utd are really getting some momentum behind them and the goals of Marcus Rashford seem to have lifted the whole club and the fans. This will be hard against a decent Watford team, but I expect United to win."
He predicts a far easier win for his former side Arsenal, who face relegation battlers Swansea City.
Arsenal fans are not at all happy after their loss at Old Trafford, with players including Theo Walcott and Alexis Sanchez coming in for criticism.
Merson predicts a 2-0 win for the Gunners, but talked up the importance of an early goal.
He said: "I'd say this is probably the biggest game of the season so far for Arsenal. Swansea had a kick in the teeth after losing from 1-0 up at Spurs and they are probably the perfect team for Arsenal to play this week because they're a nice team who won't kick Arsenal off the pitch.
"Arsenal should win - but if they don't score in the first 20 minutes, it could get very cagey."
Leicester City's draw against West Brom opens the door for Arsenal to get back into the title race, and rivals Tottenham facing a tricky trip to West Ham, the Gunners could be right back in the mix with a victory.
