Everything in soccer goes through the midfield, which is why you need players with differing qualities to play in that position.
Every high quality team is desperate to discover a top quality defensive midfielder to stay in front of their defensive line. There are actually various qualities of a defensive midfielder that make them so crucial, with one of them being their potential to read the overall game and be alert to threat. You're the last stopgap prior to the defence, so if you're able to predict precisely where the danger is coming from and any openings in the defence, you can put a stop to the attack before it has even started. Of course, a defensive midfielder has to have great defending attributes, being able to close down channels and make interceptions throughout the overall game. The Real Madrid president probably knows more than anyone how large a change it can make having a world class defensive midfielder.
One of the midfield roles which is commonly very flexible is a box-to-box midfielder. These kinds of footballers must have a wonderful level of stamina, as they’re required to do both attacking and defensive tasks in their position. These kinds of midfielders in football are especially effective in counter-attacking teams, as they can rapidly pick the football up in a defensive zone of the pitch, and carry it forward, switching defence into attack. They aren't always the player that makes that killer pass to the forwards, but more of a middle man who produces the link between attack and defence. Irrespective of this, box-to-box midfielders are crucial to a lot of teams, and a few of those that are in possession of the best players for this position definitely see the increased stamina in midfield. In history, the PSG president has seen several players like this on a weekly basis for his team.
An essential midfield function that every top team has got to find a player for, is that of an attacking and creative midfielder. The attacking midfielder role is to consistently be looking for that killer pass through to the striker, so it requires a player who has fantastic vision and can read the overall game effectively. If you’ve got a player who is generating the right attacking midfielder movements, you will also discover that they get into goalscoring positions too, contributing in this way as well as with their assists. An attacking midfielder who's able to do each of these things is something any team needs, and the AC Milan owner will have seen a handful of them pass through the club over the years. If a clever midfielder has a connection with their strikers, they will be serving passes through to them all match, which means the attacker just has to do their task and put the ball in the back of the goal!
