Manchester United were handed a bit of a reality check on Tuesday evening as the Champions League made its triumphant return.

After winning 10 out of Ole Gunnar Solskjaer's first 11 games in charge - going undefeated in the process - the Red Devils were beaten 2-0 by Paris Saint-Germain at Old Trafford.

United were outclassed and outfought by Thomas Tuchel's side, who now look all but certain to make the quarter-final stage of the competition.

Nevertheless, no one can take away what a great job Solskjaer has done at steadying the ship and it seems only a matter of time before they are back competing for Europe's biggest prize.

The summer transfer window could prove pivotal in that coming to fruition quickly, with some world-class reinforcements needed.

United also need to shift some deadwood from their squad and Romelu Lukaku could be shown the exit door after just two years in Manchester.

As reported by the Mirror, the Red Devils will look to use the £75m striker in a deal for either Paulo Dybala or Mauro Icardi.

Both Argentine strikers would command fees of around £100m, so United are keen to bring that down by including Lukaku in any package.

The Belgian is aware of the club's stance on him and is said to prefer a move to Turin to link up with Cristiano Ronaldo.

Dybala has failed out of favour at Juve under Max Allegri, with Ronaldo assuming the role of talisman in attack.

As for Icardi, the former Barcelona academy man has been stripped of the captaincy and his future at the San Siro looks far from certain after issues surrounding his agent, Wanda Nara.

Given United's change in style since Jose Mourinho's exit, either Dybala or Icardi would be far better suited to the team than Lukaku.

The Mirror also report that United are keeping tabs on exciting Benfica youngster Joao Felix and highly-rated Lyon midfielder Tanguy Ndombele.

It looks set to be a busy summer at Old Trafford.
