Manchester United interim boss Ralf Rangnick states that Cristiano Ronaldo cannot play up front on his own next season.

The Red Devils will have to deal with numerous personnel matters in the off-season, including the future of Ronaldo.

While Rangnick has praised the Portuguese veteran for his contribution in recent weeks, he believes United need to recruit forwards to ease the burden on Ronaldo's shoulders.

He said after a 3-0 win over Brentford: "Cristiano is not a central striker. He does not want to play in that position, in order to not play central, you have to play two strikers. If you look into international football, there are not many teams who play with two, you either have three or a false nine.

"It's not a question of a position, the club needs two new strikers who give this team more quality.

"Modern strikers do not have to be wingers if you look at Liverpool and Man City, they have top strikers. Gabriel Jesus has hardly played and now he's playing regularly. If you ask me if he's a central striker or a winger, is Grealish a striker, they can switch and rotate.

"We don't have that many. Mason Greenwood would have been those players, but he's no longer part of the squad. Martial went on loan at Seville, Cavani has been injured."
