His time at Athletico Madrid was very promising, and he had a good couple of seasons with Liverpool but something changed and he's never recovered. Great business to get £50m for a player they no longer wanted
Suarez wasn't an exciting signing, when he joined Liverpool very few people expected him to produce but he became a top quality striker whilst there.
The last signing that impressed me was Torres and that was years ago
Very poor squad, he has to try and undo 10 or so years of transfers who are very costly and hugely overrated. I cannot remember the last signing they made that was a decent player or world class
