Despite spending approximately £150 million on new signings last summer, Jose Mourinho STILL isn't content with his Manchester United squad.
Manchester City's dominance in the Premier League this season has led Mourinho to believe he can't compete with Pep Guardiola financially.
In the Portuguese's defence, Guardiola has spent £100 million more than him since they both arrived in Manchester 18 months ago, but that's not entirely why he's second best.
So what does Mourinho plan to do about it? Speaking last week, he suggested there will be a lot of change when the 2018 summer transfer window comes around.
"I don't want to take any credit away from what they (City) are doing," he said. "I think next season we are going to get two or three more players and also lose two or three.
"It's not going to happen that there is a dramatic change and a dramatic improvement but with time, step by step, with some balance, we have to do it."
But with 16 game weeks remaining of the 2017/18 Premier League season, if United are to have any hope of catching City now, money must be spent in January.
And according to the Daily Mail, Mourinho is prepared to do just that if the right players become available.
More specifically, United have informed agents that they're currently on the lookout for two new full-backs - presumably on both flanks - and an attacking midfielder.
With Antonio Valencia now well into his 30s and currently out injured, it makes sense for Mourinho to start looking for his eventual replacement at right-back.
As for left-back, Luke Shaw may have returned for United recently but strength in depth is vital for any side looking to challenge for silverware.
And in attacking midfield, Henrikh Mkhitaryan has struggled this season while Juan Mata's contract expires in six months' time, although a new deal is reportedly imminent.
Paul Pogba is another contender for the No.10 role, however, and judging by his performance against Everton on New Year's Day, he could be the man to fill that role permanently.
Thierry Henry certainly thinks so anyway. He said: "[Pogba] can play in a lot of positions. I said when he first arrived that, for me, he is not a holding midfielder.
"He can play in a lot of positions but that is where he is at his best (attacking midfield). That was vintage Juve Pogba.
"When he plays at that level he is almost unplayable and I think he changed the second half. He went up to a certain level."
