He's spent a fair bit. Joelinton, Saint-Maximin, Krafth, Wilson, Lewis and Willock is around £130m, in that time Perez is pretty much their only sale of note. So around £100m net across five windows.
He's been appalling, so many games where they've been battered, had around 20-25% possession, barely a shot on goal and somehow jammed a point or even all three. Comfortably the worst team in the league to watch while he's been there.
Case in point, before they scored at Molineux (41 minutes or something) they hadn't had a single shot, on or off target, and the goal was entirely of our own making rather than them doing anything. As soon as they equalised, they started timewasting and were clearly happy to play the rest of the game out and leave with a draw. Didn't create a single decent chance after we went back in front. Left Joelinton on for 90 minutes because reasons. Willock didn't even last until half time because Bruce picked him despite being injured in the first place.
Drew here last season after they got the softest free kick in the world in the 93rd minute. That free kick was their only shot on target of the entire second half.
