But Jose Mourinho will be acutely aware that Manchester City are some way ahead of their rivals, and that more spending will be required in the summer.
As for Watford, head coach Javi Gracia made three changes to the team that started against Newcastle United last weekend, with Heurelho Gomes, Gerard Deulofeu and Richarlison coming in for Orestis Karnezis, Etienne Capoue and Troy Deeney.
"It's hard because he is my friend, 17 years is a long time", Mourinho said after beating Watford.
"17 years.in Leiria, Porto, London, Milan, Madrid, London again and Manchester", said Mourinho.
He'll join Jose Mourinho's coaching staff next season and, who knows, further down the line he might be the first United old boy since Wilf McGuinness to become the club's full-time manager.
'I will have specific coaches, analysts and no assistant manager. I was fine once I got here but in the hotel before I left, it was mixed emotions.
Carrick spoke to the fans after the win, thanking them for all their support over his 12-year career at the club, where he has lifted every trophy possible. I will never forget Luis Figo's last match at Inter Milan. "But if it's impossible to play today, I have my doubts".
"This is an unbelievable place to play football and it's the greatest club in the world".
However, throughout the match, the most noticeable squad absentee was Anthony Martial. "He was injured, he was injured Friday training session, yesterday couldn't train".
Mourinho had a lovely message for his old friend before the game, wishing him the best of luck, expressing his gratitude and admiration for a man he regarded as a student and confidante.
In stark contrast, their FA Cup final opponents Chelsea had a torrid time at St. James' Park, losing 3-0 to Newcastle United as their top four hopes fell apart. I'm not sure if he can do it for 90 minutes, but even if he can, I will bring him off so he can come off on his own.
