Unpopular opinion here, but I really have doubts about Kovac's quality.
I watch a lot of Bundesliga and Ligue 1 and his sides have never impressed me at all. Now, I'm not claiming to be a know-it-all here, football is a game of opinions and I am just sharing mine. But from what I've seen (based on the eye and not stats), his teams don't play good football on the whole and don't press (a key component of the modern game). He also is an extremely divisive figure and seems to cause consternation wherever he goes.
I know on face value his win% etc looks good, but these were massively padded by his time at Bayern. I haven't seen as much of his sides as I have of other coaches (Galtier for example) but I really don't get the fuss. I have asked others who watch a lot more European footy than I do and they all seemed to agree.
Now, I know he might still be the best of a frankly awful list of candidates, but I am surprised to see so many people lauding him on here. He might turn out to be great, but from what I've seen, I have my doubts ?
