Paul Merson believes Manchester United should have signed new Chelsea midfielder Saul Niguez.
The Spanish midfielder, who won the La Liga with Atletico Madrid last season, joined Chelsea on loan with the Blues having an option to sign him permanently.
“Chelsea now have a midfield dreams are made of after getting Saul Niguez on deadline day,” Merson told Starsport.
“What a phenomenal signing that is. He’s in his prime. He’s just won La Liga. He plays in all the big games. And you get him on loan. That’s amazing.
“He’s only going to cost £30m if they make it permanent as well. Where do you ever find players like that for that kind of money? Amazing.
“Chelsea already have three great midfielders in N’Golo Kante, Jorginho and Mateo Kovacic. He’s the fourth.
“And they are going to need him. They are going deep in every competition this season. They need players.
“I don’t know why teams like Manchester United and Arsenal didn’t go in for him. Look at their midfields.
“United have Paul Pogba but he can’t play in a two and then it’s Fred, Scott McTominay and Nemanja Matic.
“And Arsenal ended up handing a new contract to Granit Xhaka… The difference in class is enormous.”
