I like him, based off Feyenoord match highlights. Team is well coordinated in both phases, reacts quickly to game situations in an organised manner - which is always a good starting point to assess and know that a lot of coaching work has gone into the side.
He's no man-manager bluffer, he's a coach first. The rest, if it gives him 'charisma', great.
You see the quick short passing and high press, which fits us fine, but also there's a defensive solidity there, which we lack.
If he can modify the shape we play now to make us more compact, while taking in aspects of that consistent high press from Feyenoord...we could easily improve in our play compared to this season.
This really stands out now I've watched highlights of his Feyenoord team - they're very deliberate in what they do, a huge number of first-time passes, but the players just generally seem to move the ball around incredibly quickly.
Watching us lately, sometimes feels like a few too many of our players want an age and about 4-5 touches standing more or less still before they decide what to do with the ball, which is something that has crept into our game more and more over the past 1-2 years. Could be some teething problems as the players get used to it, but on the face of it we have players with the required technical ability to play more quickly with the ball that we currently seem to.
