Jose Mourinho is usually at his best in his second season at a club.
And with the Manchester United boss taking his side on the longest unbeaten run in Europe’s top five leagues, it is clear his influence is starting to show.
That will surely mean Mourinho gets even more control over who comes into his squad, with names like Antoine Griezmann being linked to the squad.
And there will be a number of players who need to use the rest of the season to prove themselves.
We look at those who have an uncertain future at Old Trafford.
Ashley Young has made just 11 appearances in all competitions for Manchester United this season, and there is no doubt he is unhappy at Old Trafford.
He probably would have made a move to China with Shandong Luneng interested, but Mourinho vetoed the move as he saw the former England winger as a crucial part of his squad.
The 31-year-old is under contract until 2018 at United, but it would be a massive surprise if he stays in the summer.
Expect him to complete that move to the Chinese Super League – our Football Whispers Index rates a move at 3.7.
David de Gea
David de Gea’s failed move to the Bernabeu in 2015 isn’t one that will be forgotten easily.
While Keylor Navas is a very good goalkeeper, de Gea is a class above and the Madrid hierarchy must rue that fax machine to this day.
It is clear that a goalie will be top of their shopping list when the transfer window opens, and de Gea will rival Thibaut Courtois and Hugo Lloris for a potential move to the Spanish league leaders.
And it would be no surprise if the biggest club in Spain went for the Spanish No.1 – they had that for years when they had Iker Casillas, and could repeat that with de Gea.
And The Manchester United man refused to rule out a move to Madrid when asked by AS.
“Nobody knows the future,” he said.
“The future is the future, I’m very happy at United, it’s a great club. In England, the football is enjoyable.
“I will not talk about that [a move to Madrid].
De Gea is originally from Madrid and it would not be a surprise if he wanted to move home, despite having more than two seasons left on his contract.
Many at Manchester United thought they had bought a left-back for the next ten years when Luke Shaw arrived from Southampton.
But Mourinho publicly questioned his mentality in November after Shaw ruled himself out for the match against Swansea.
The Portuguese boss called on the left-back to change, saying: “There is a difference between the brave, who want to be there at any cost, and the ones for who a little pain can make a difference.
“If I were to speak with the many great football people of this team, they will say many times they played without being 100 per cent.
“For the team you have to do anything. That is my way of seeing.”
And that has clearly influenced Mourinho’s thoughts on Shaw, who is no longer first choice at Old Trafford.
He will need to prove to his boss he is worth keeping around, or he may find himself heading for the exit door come the summer.
We have the 21-year-old as 1.1 to join Tottenham on our Whispers Index.
Juan Mata can tell Anthony Martial that your reputation doesn’t stop Mourinho from selling you.
Yes, he may have scored against Watford, but there are clearly issues between the Portuguese manager and the French winger.
We rate him at 1.1 to join Paris Saint-Germain.
Dont listen the papers it's wrong thanks Come on United ?

The 21-year-old may have told fans to ignore the papers on Twitter, but with his agent admitting he held talks with Sevilla, it’s fair to say he isn’t guaranteed to stay at Old Trafford.
But if he can produce more moments of magic like the one against Watford, he’ll play his way into Mourinho’s plans.
It’s undeniable that there was a very long courtship between Mourinho and Wayne Rooney.
The current Manchetser United manager thought he’d convinced the Engalnd captain to join him at Chelsea during his second spell at Stamford Bridge.
But the hope that Rooney may become the Rooney of old under Mourinho has faded, and he was linked with a January move to China.
Rooney is still a very good player, but at 31, he is now past his best.
He is now the record goalscorer for Manchester United, so he can’t really say he has much unfinished business at Old Trafford.
Unless he goes on an unbelievable run, which he hasn’t done for the last few years, it would be no surprise to see the Red Devils move their captain on come the summer.
Michael Carrick has been a stalwart of Manchester United squads over the years and he has been a key performer for Mourinho’s side this season.
His age is a problem for Mourinho as he decides on his future as they work out whether to extend his contract, which runs out in the summer.
Indeed, according to The Mirror, the Portuguese boss said: “Look, let’s be honest, I see many positive things in Carrick.
“But I cannot go to his identity cards and delete five years. He is 36, he is not 30.”
He has been linked with a surprise move to Arsenal, and while it would be a surprise to see him turning out for one of United’s top-four rivals, Carrick undoubtedly still has something to offer clubs towards the top of the table.
