It was a job well done for Louis van Gaal as his first season at Manchester United ended with a fourth place finish and with it qualification for next seasons Champions League.

But while it marked a significant improvement in terms of results from the previous year, the Dutchman knows there is still plenty of work to be done as he continues to build a squad capable of challenging for the Premier League in the not too distant future.

The Red Devils have already announced the signing of PSV star Memphis Depay who is sure to be a strong acquisition, and with links to a host of other players it promises to be a busy summer at Old Trafford.

But with new arrivals; there are sure to be a few departures also and for some it appears their time with the Premier League’s most successful club could be coming to an end.

With uncertainty surrounding their futures; here are five Manchester United stars that could be facing a summer exit...

Adnan Januzaj

Manchester United's Adnan Januzaj

Much was expected of Adnan Januzaj when he burst onto the scene during David Moyes’ reign at Old Trafford, but his career at United has failed to get going.

The Belgian winger scored twice on his full debut at Sunderland back in 2013, but since then has failed to hold down a regular position in the starting line-up; finding himself limited mainly to substitute appearances.

The arrival of Memphis Depay won’t have done much to help his cause, and a possible loan deal could be the best option for the 20-year-old in order to continue his development with both Everton and Real Sociedad possible destinations next season.

Spurs have also been linked with a move for the midfielder, but given his potential the Red Devils would be keen to hang onto him for a little while longer.

Nani

Nani

Another winger that looks to be heading for the Old Trafford exit is Portuguese star Nani.

The 28-year-old has shown plenty of flashes of brilliance during his time at United, but his inconsistency has proved the downfall; and it appears the club are ready to move him on.

Nani spent last season on loan at Sporting Lisbon where he put in some impressive displays, although this hasn’t done enough to convince Louis van Gaal that he still has a future with the Red Devils.

Roma and Inter Milan are believed to be interested in a deal of around £10m, but his £100,000 a week wages could still prove a stumbling block.

Javier Hernandez

Javier Hernandez

Mexican striker Javier Hernandez was another of United’s players to spend last season on loan; this time with Real Madrid.

Despite scoring seven goals for the Spanish giants, Hernandez was unsurprisingly used sparingly with the majority of his appearances coming from the bench.

Madrid decided against making his move a permanent one, and it’s thought United are willing to let him leave this summer as he doesn’t feature in the manager’s long term plans.

Reports suggest Inter Milan have lodged a bid of £8m for striker, but the Reds are keen to hold out for £10m and with a number of Premier League clubs after his signature; he could be set to stay in England.

David de Gea

Goalkeeper - David De Gea

One man who looks certain to be leaving Manchester United is their star man David de Gea with his move to Real Madrid surely due to be completed sooner rather than later.

De Gea enjoyed another terrific season in goal for the Red Devils, with his performances ensuring he has become Madrid’s number one transfer target this summer as a replacement for long serving shot stopper Iker Casillas.

The 24-year-old is thought to have already agreed personal terms with the Spanish giants, with just the transfer fee left to sort out before he completes a move back to his homeland.

De Gea has just one left on his contract meaning United may struggle to bring in the £35m valuation they have slapped on the Spaniard, with Madrid looking to pay closer to £25m for his services.

Robin van Persie

Robin Van Persie

It seemed inconceivable not so long ago that United would consider selling Robin van Persie, but following a disappointing campaign with the Red Devils; his time at the club could be nearing an end.

The Dutchman struggled for both fitness and form last term netting just 10 goals, and with the team seemingly performing better in his absence; his future has been placed in major doubt.

Van Gaal is keen to bolster his attacking options during the transfer window, and with Lazio and Juventus keen on a £10m deal for the the 31-year-old; Van Persie has been left to consider his future with no promises about regular first-team football should he stay at Old Trafford.
