Phil Thompson on why Luis Suarez may thrive in the Old Trafford pressure cooker
Lou Macari on why Manchester United will fear Suarez on Sunday
"Suarez is a concern, as is anybody who has scored 19 goals in a team that's in the position that Liverpool are in. It shows what a player he is. We've all talked about Suarez time and time again this season about other things than his goalscoring, but I think if you concentrate on what he's best at - which is scoring goals - then he's a problem to you. If you give him any amount of time and room in that box then he will punish you. That's why I'm not over-confident that United will win on Sunday. People like Suarez and Steven Gerrard can't be written off. There are other players in the Liverpool team, but I look at their position at this moment in time and I don't remember Liverpool being 21 points behind United going into the second half of the season and only for that reason do I say it's been a disastrous season. Liverpool supporters don't remember occasions like that, going into a game against Manchester United 21 points behind. If United play at their very best then as far as I'm concerned they will win the game, but I am worried about Suarez."
Iain Dowie on the merits of the two in-form frontmen
"Ahead of Man United-Liverpool everybody is talking about Robin van Persie and Luis Suarez, who are the best centre-forwards in the Premier League by a country mile. Van Persie is the complete striker and there is nothing he cannot do; his touch is sublime, he has got great pace and his finishing is a revelation. Suarez, meanwhile, has great acceleration over a short period and he can score all types of goals so United cannot afford to leave space in behind and have to make sure they are tight when he has it at his feet. He might move into a deeper position to accommodate Daniel Sturridge, but I think that would be a dangerous move as he has been so good as that lone frontman."
Stewart Robson on why Manchester United have more goalscoring threat than Liverpool
"Even though Manchester United haven't been good defensively this season, they've been at their best in attacking areas. They've created opportunities, they've scored goals and key to that has been Robin van Persie, but also Javier Hernandez over the Christmas period has looked to be back to his best. He's been alert and aware around the box. He had four or five really good opportunities when he came on against Newcastle. He didn't take them, but he kept on making the right runs. His awareness in and around the box and his determination to get Manchester United back into the game and to win the game was excellent. As for Liverpool, we saw the best and worst of their traits over the Christmas period. In the game against Stoke they started off really well, but were beaten by some poor defensive play, particularly when balls were played at the back four. They have been at their penetrating best in the last few weeks though; earlier in the season they couldn't score goals and now they look as if they can score goals and Suarez has been outstanding. But at the weekend I still think Manchester United will have too many areas where they can score goals for Liverpool to win the game. I think Manchester United will win the game 2-0."
