I don't mean to post a seemingly negative thread after a win but is anyone else left bewildered by some of Bulut's use of subs?

There's been a few games this season where the shape changes have led to negative results and the choice of players to be replaced have usually been our better players. Today for example I thought Colwill was the best player on the pitch for either side and the game completely changed once he went off (although he could've been blowing/injured I'm not sure). I also thought JC had one of his better games all season before going off. Think we were fortunate to hold on in the end thankfully.

Not looking to rip into Bulut for the sake of it as think overall he's doing a great job but definitely an area for concern all year in my eyes.
