Nani has scored four goals while on loan at Sporting Lisbon Getty Images

Manchester United winger Nani says he has not heard from manager Louis van Gaal since going on loan to Sporting Lisbon for the duration of the season.

The Portugal international was loaned out following the 2014 summer signing of Angel Di Maria from Real Madrid and has scored four goals in 18 league appearances back with Sporting.

However, in an ominous sign over his long-term United future, Nani has revealed how he is yet to be contacted by Van Gaal during his spell, only hearing from executive vice-chairman Ed Woodward after his goal against Gil Vicente.

Though loan players are rarely in constant contact with their parent clubs, it comes as a surprise that Nani has not once spoken with Van Gaal during the first six months of his loan spell and draws questions over his career at United.

"No [I have not spoken with Louis van Gaal]," the 28-year-old told the Daily Mail.

"I receive some texts from Ed Woodward. He texted me about the goal and the great season I am having here. I used to speak to Antonio Valencia but I changed my number so it's difficult."

Nani's opportunities in recent seasons at United have dwindled, having made just seven league appearances in each of the last two campaigns.

Though his spell back in the Portuguese capital has seen Nani rediscover his best form, he is unsure whether he has impressed sufficiently enough to break back into the United team.

"At the moment I just focus on my job here," he added. "I'll do my best and get in the best condition I can, then come back as strong as possible and see what the manager or the club want from me.

"I love Man United. I love the club. The only decision I made to go away was to play more and be me again because I lost a lot of things there last season because of injuries and the change of the manager.

"The new manager didn't know me well and a lot of things changed. I needed to play regularly to be happy.

"You never know the future. It depends on a lot of things. If Man United want me to stay then, with different mentality I think we can work well next season but it's a lot of things to discuss and see."
