Manchester United manager Jose Mourinho has already made two signings this summer in the form of young right-back Diogo Dalot and central midfielder Fred, but the Portuguese is unlikely to be finished there as he looks to make his side serious challengers to Manchester City in the Premier League, as well as a force again in Europe.

The Red Devils boss may need to offload some names before he brings more new faces to Old Trafford, and he will certainly hope to ramp up his business soon given the transfer window slams shut early on August 9 this year.

The 55-year-old will be working in conjunction with Ed Woodward to identify the individuals that will help the club take that next step needed to compete for the English top flight title and in the Champions League, and strengthening his frontline may well be a priority if he is looking for more depth out wide and a back-up option to Romelu Lukaku up top.

While the former Chelsea chief, who has been urged to sign a £63m World Cup attacker by fans with one saying "sign him up and sell lazy Martial", will have the stars in mind that he wants to bring to Old Trafford, perhaps he should also be considering bringing some familiar faces back to Manchester too, as there are ex-Red Devils out there that would make a big difference for them on the pitch now in their bid for even more trophies.

Here are three former Man United players Mourinho must look to re-sign this summer…

Hopes were high when the exciting winger joined United from Crystal Palace in 2013 that he would make a huge impact at Old Trafford, but the move came perhaps a little too early and after just four appearances in all competitions for the Red Devils, he rejoined the Eagles on a permanent deal in 2015.

The 25-year-old has become a key man since then, and his nine goals and five assists in 29 top flight matches last season helped the south London outfit recover from the worst start in Premier League history to secure an 11th-place finish.

He would certainly bring excitement and unpredictability to the United attack, and his ability to play out wide or through the middle would make him a huge threat for opposition defences.

Like Zaha, Depay proved to be something of a flop having moved to Old Trafford from PSV Eindhoven in 2015, and he left for Lyon having scored just seven goals in 53 appearances for the Red Devils.

However, the left-sided player has clearly matured and improved for the Ligue 1 outfit, and 22 goals and a further 17 assists in 51 appearances in all competitions last term show the quality that he can bring.

If he did arrive at Old Trafford he could play on the left side of a front three, which would see Alexis Sanchez move to the opposite flank and solve Mourinho's right wing issue.

The Independent reported on June 8 that Mourinho will prioritise signing a new back-up striker to Romelu Lukaku instead of splashing out on a new left-back this summer, and former fan favourite Hernandez would surely be near the top of his list of options.

The Portuguese boss has admitted previously that he would never have sold the Mexico international had he been the manager when the 30-year-old left for Bayer Leverkusen in 2015, and with his impressive goal record and Premier League experience he could prove to be a great addition, and one that may not cost too much considering he doesn't appear to be guaranteed a starting spot at West Ham United right now.
