United are on the longest unbeaten run of any club in Europe's top five domestic leagues and moved above Liverpool into fifth place with 48 points before Liverpool host second-placed Tottenham Hotspur (50) later.
Manchester United cruised to a 2-0 win against Watford in the Premier League at Old Trafford on Saturday. "We want to get to a more steady state, and to be buying and potentially selling a lower number of players each year".
However the Manchester United manager offered a far from glowing assessment of the champions-elect.
Jones may be absent but United's defensive options have been boosted by the return of Eric Bailly from the Africa Cup of Nations and Mourinho was pleased with how the Ivorian played against Leicester in his first game back.
"But because it's my team, you'll just say it was very good - and that's fine - but it was very good".
"Sometimes you get disappointed because you expect more and even in relation to this everything is balanced".
"It was a hard match and a very important win for us. I have always said from day dot if somebody comes in and they give me a chance to play and play regularly then they will get the best out of me".
"So they are one of the clubs that I am not anxious about at all".
Napoli and clubs in China and the United States have been linked with the former Paris Saint-Germain striker in recent days, but Mourinho is confident he will remain in United red next season.
"Because I think he's still missing a little bit of confidence, I kept shouting to him: attack the defender, go to the one against one - he needs that confidence".
He scored with a stunning scissor kick three minutes into his debut in a friendly against Galatasaray, hit a late victor against Leicester to land United the Community Shield in August, the traditional curtain-raiser to the season, then marked his first Premier League start with a long-range strike against Bournemouth. Martial scored the second goal against Watford to give United an unassailable 2-Nil lead.
None of us doubted Martial's ability to bounce back and he vindicated that with what was a sizzling display against a Watford team which tried to be resolute right up until the final whistle.
