With all the media speculation surrounding Paul Pogba's imminent arrival at Old Trafford, the news has not gone down well with many as the financial side of the game continues to rise to obscene levels.
One man who has made it very clear that he has no intention of joining in the over the top spending is Liverpool boss Jurgen Klopp, who has claimed that even if he had the power to go out and sign a player for £100m, he wouldn't do it as he wants to manage in a different way.
It's a thinly veiled dig at Mourinho, who has green-lighted a spending spree at Manchester United in an attempt to revamp their underperforming squad, and it will likely be something that Liverpool fans like the sound of.
Klopp has never been at a club where big name signings are the norm, and yet he managed to make Dortmund into one of the finest sides in Europe, and that is because he values the team unit as a whole over signing the best players available.
If you bring one player in for £100million or whatever and he gets injured then it all goes through the chimney.
The day that this is football, I’m not in a job any more, because the game is about playing together. That is why somebody invented passes so these players can play together. It’s not about running with the ball because you can do it all the time.
Building the group is not my unique idea – it is necessary to be successful in football. Other clubs can go out and spend more money and collect top players, yes. Do I have to do it differently to that?
Actually, I want to do it differently. I would even do it differently if I could spend that money.
I don’t know exactly how much money we could spend because nobody has told me up to this point ‘no, no, no you can’t do this’. If I spend money it is because I am trying to build a real team.
You can win championships, you can win titles. But maybe there is a manner in which you want it. It is about how it is.
Mourinho is highly unlikely to be bothered by Klopp's comments, but it is interesting to see the Liverpool manager speak with such clarity in terms of what he doesn't believe in with the media obsessed with the arrival of Pogba.
Mourinho vs Klopp is going to be a fascinating aspect of Manchester United's meetings with Liverpool this season, and all that comments like the above do is serve to build up the anticipation for the new season even more.
