I know I'll get some stick for this but I always felt that KLP was over hyped - he was (is) a good player but lacked the physical strength (and sometimes courage) for the highest level. He's often compared to Bowen who was no giant but had much greater physical presence and this has obviously been worked on by West Ham. I haven't seen much of KLP of late but suspect that, strengthwise at least, he doesn't compare well with those above him in Brentford's pecking order. I do think that this wasn't an issue with Brennan Johnson who really was the better prospect overall.
He was imo, he's a talented boy and absolutely deserved his chance, but I doubt he'd be held in such high regards if he wasn't a Hull lad.
He's stalled somewhat since his move, a loan to kick start things for him would probably be the best bet for him. Getting 10/15mins as he has so far this season, isn't going to help him.
