KEVIN MORAN, Jose Antonio Reyes and Pablo Zabaleta – that's the answer to the quiz question which three players have been sent off in an FA Cup Final – and Mark Clattenburg is 4-1 to add to that list in normal time on Saturday.
Marouane Fellaini returns from suspension and the big Belgian is bet365’s 9-1 co-favourite of four to be first into Clattenburg’s book while the whistler is 11-4 to award a penalty.
Bet365’s Steve Freeth said: “Clattenburg issued just six Premier League red cards combined in the two seasons prior to the current one but half of those featured Vidic, Blackett and Shaw while Palace's Dwight Gayle was given his marching orders by the referee in October.”
United's FA Cup Final preparations were disrupted by a fake bomb scare but I'm on them to produce an explosive display at Wembley.
Louis van Gaal resisted the temptation to rest players after their final Premier League match with Bournemouth was moved to Tuesday.
The Dutchman was rewarded with a 3-1 win that clinched fifth place but players will be slightly more leg weary than their opponents.
However, they have some momentum with eight wins in 11 and players in form including young French forward Anthony Martial and England Euro 2016 prospect Marcus Rashford.
Martial has justified his huge transfer fee and has been involved in exactly half of United's 12 FA Cup goals this season (two goals, four assists). He is 6-1 at McBookie and Ladbrokes to score first and 23-10 with William Hill at any time.
Rashford has bagged eight goals from just 14 shots on target for United in all competitions – and that's an incredible return and one reason why Roy Hodgson is having closer look before finalising his squad. The teenager is expected to start and is 11-2 at bet365 to score first and 2-1 with bet365 at any time.
Palace can't be ruled out as they've been pitch perfect in the Cup with three wins against Premier League opponents and another against Reading with no replays.
Palace don't have as many star men but winger Yannick Bolasie has been used in the No.10 position to good effect and his pace on the counter attack could trouble United.
The most likely scorer is Connor Wickham, who netted twice in the semi-final success against Watford, and is 11-1 at bet365 to bag the opener and 9-2 to hit the target.
Last time the sides met in the Final it was a 3-3 thriller but no one expects this one to be goal-laden. It should be tight and tense and I'd favour under 2.5 goals ahead of overs. That pays 3-5 at McBookie.
United's favourite scorelines have been 1-0 and 0-0 and Palace are not prolific so there's even a chance of under 1.5 goals at 2-1 with William Hill especially if Old Trafford keeper David de Gea plays a blinder.
