Sunday's clash between Manchester United and Liverpool has a lot more at stake than just pride.While the home side are vying to hold onto fourth in the Premier League as Arsenal and Chelsea look to close the gap, Liverpool can move three points above Manchester City at the top.City have played one game more than the Reds, who are undoubtedly under more pressure at the moment.Predicting United and Liverpool's starting line-ups for the game is no easy task given their respective injury problems, so here's how they could look.Manchester United: David de Gea; Ashley Young, Chris Smalling, Victor Lindelof, Luke Shaw; Nemanja Matic, Ander Herrera, Paul Pogba; Juan Mata, Romelu Lukaku, Marcus RashfordLiverpool: Alisson; Trent Alexander-Arnold, Joel Matip, Virgil van Dijk, Andy Robertson; Georginio Wijnaldum, Fabinho, Naby Keita; Mohamed Salah, Roberto Firmino, Sadio ManePicking a winner for Sunday is no easy task, but looking at the predicted line-ups Liverpool are arguably the stronger side.A lot depends on whether Jesse Lingard and Anthony Martial will be back for United, though, because if they are available, they could start ahead of Mata and Lukaku.A front three of Lingard, Rashford and Martial would represent a daunting challenge for Liverpool given their recent form.Rashford will be a particular threat - the 21-year-old has five goals in his last six Premier League games - and Jermaine Jenas claims he would take him over Liverpool's Firmino.And yes, you've read that right.Ahead of the weekend's football on BT Sport, Robbie Savage led the 'Gone in 60 Seconds' game as he asked his guests a series of big questions.And when Savage asked: "Would Rashford start for Liverpool?" Jenas replied: "Ahh, yes," before adding: "Firmino," in reference to who would drop out. Check out the video below.

Debatable. Firmino is unquestionably the most under-appreciated player in Liverpool's front three and the job he does for them is fantastic.

The 27-year-old holds the ball up extremely well and, when given the chance to, he's very good at finishing. It's just a shame he doesn't score more goals.

Rio Ferdinand reacted to Jenas' comment with a tweet of his own and it seems he agrees with his BT Sport colleague.
