Although Jose Mourinho has made his desire to add a fourth major signing of the summer to his Manchester United squad pretty clear, the Portuguese boss has already manufactured a very well balanced setup at Old Trafford.

Following the arrivals of Victor Lindelof, Romelu Lukaku and Nemanja Matic, Mourinho's men look more than capable of challenging for the Premier League title this time around.

They got their domestic campaign off to a flying start on Sunday with a comprehensive 4-0 win over West Ham.

Paul Pogba sealed the win with a brilliant fourth goal in the game's closing stages after a brace from Lukaku and another strike from substitute Anthony Martial had already put the Red Devils into a commanding position.

Despite impressing during pre-season and in his cameo on the opening day, there have been doubts over the future of United's third goalscorer, Martial.

Now into his third season at Old Trafford, Martial is expected to kick on and reach his undoubted potential.

Nevertheless, the 21-year-old is yet to nail down a regular place in the starting XI which has encouraged some clubs to register their interest.

Inter Milan have been heavily linked with making a move for the Frenchman but have so far seen their efforts rebuffed by Mourinho and co.

And now Martial's cousin, Jema, has spoken out about the former Monaco ace's future at the club before quickly deleting it.

According to the Manchester Evening News, the tweet appeared to confirm Martial will be staying at Old Trafford for at least another year.

"For Manchester United, Anthony's departure is not a possibility, even on loan. They rely on him."

The tweet can no longer be found on Jema's profile but United supporters will still be relieved all signs suggest the forward is staying put.

Martial could make his first start of the campaign when Mourinho's men return to action on Saturday with a trip to face Paul Clement's Swansea side.
