Michael Owen insists Manchester United must keep hold of David de Gea

Former Manchester United striker-turned pundit Michael Owen believes that Jose Mourinho will have set his sights on keeping goalkeeper David de Gea following the £75m signing of Romelu Lukaku.

The Belgium international arrived from Everton earlier in the month after the Red Devils fended off interest from rivals Chelsea to pursue his signature. Lukaku has since adapted well to the Red Devils' style of play after having bagged two goals in three pre-season friendlies.

Speaking to Metro, Owen insists that United have managed to fill the striker void with the signing of Lukaku, and the emphasis will now be on keeping De Gea, who continues to be linked with a move to Real Madrid.

He said: "You look at their squad and it’s hard to find any chinks in the armour. What players will become available now that would improve their starting XI? The main thing was a centre forward and they’ve done that. The key for Manchester United now is keeping David De Gea – if they lose him that will definitely weaken their side. There’s no-one out there who will improve that position. Keeping him is a huge thing if they can do that."

Meanwhile, Jose Mourinho has also assured that De Gea would not be sold during the summer transfer window as the shot-stopper is content with his progress with United, who are back in the Champions League next season.

The Special One opted to use goalkeeper Sergio Romero for the Red Devils' Europa League campaign last term, but he admits that he may rotate his options this time around with De Gea likely to want to participate actively in Europe's premier competition. The former Atletico Madrid star has been one of the standout performers for United in the past few years, and this has earned him a place in the PFA Team of the Year in each of the last three campaigns.
