Dimitar Berbatov says Manchester United need to be more focused on taking their chances when they face Liverpool today.
The Reds face their fierce rivals for the second time in a week after drawing their Premier League clash at Anfield last week 0-0.
In that game, Paul Pogba and Bruno Fernandes both saw late chances saved by Liverpool goalkeeper Alisson as United came closest to winning the game.
Speaking to Betfair, Berbatov argued that it will be impossible to spring any surprises on Jurgen Klopp's Liverpool side due to how well Premier League teams know each other.
Instead, the former United striker said it is a case of playing similarly to last weekend, just with an increased concentration in front of goal.
He said: "Once again, United will play Liverpool, seven days after their 0-0 draw. They can't really surprise each other. The teams know each other so well.
"United know they have a chance and will have chances in the game. This time they need to be more concentrated about taking their chances and being solid at the back.
"Both teams will try to outsmart each other. But sometimes when you play so many games against each other it is difficult to surprise each other.
"The FA Cup is very important for United. Every competition and game is. They are flying high in the league at the moment.
"Every trophy is important. They should aim high, field a strong team with one or two changes to give people a chance to play. But overall, go strong and try to win it.
"It will be a big obstacle removed if they can beat Liverpool. It will be a giant step towards winning it, but they won't be nearly there as they will have other teams to face in it."
