Manchester United are keeping tabs on Atletico Madrid midfielder Saul Niguez, according to the Daily Telegraph.

Manager Ole Gunnar Solskjaer is after two midfielders this summer and is expected to make a move for one of them, Newcastle’s Sean Longstaff, this week.

The United boss is said to be leaning towards Sporting Lisbon’s Sporting Lisbon as the other target, but Niguez is a player who has also been considered.

The 24-year-old would, though, be an expensive purchase. He has a €150m (£134m) release clause which would need to be met for Atletico to sell up.

Diego Simeone’s side are not short of money, having sold Lucas Hernandez for €80m this summer, while Antoine Griezmann is expected to be offloaded to Barcelona for €120m, with Rodri likely to join Manchester City for €70m.

Even if a large portion of that cash is spent on Benfica’s Joao Felix, the Spanish side will still have a sizable surplus for this summer, making any move for Niguez extremely difficult.
