I'd agree if DCL was on fire, scoring left right and centre, I wouldn't suggest giving Chermiti a chance. How many chances has Keane been given, despite being crap. Yes I'm fully aware managers know things we don't attitude of players and fitness, so on a so forth. However when Martinez puts Niasse on when we are 2 -0 up against West Ham and then when we are losing 2-0 to Arsenal puts Jagielka on instead of Niasse. We can't give Beto any service against Arsenal, so replace him with DCL, we concede a minute later. Our problem was in midfield, I said to my mate in the pub it would be the dumbest sub to make and it cost us. If Beto was tired and Dyche brought on DCL and a midfielder that would have been an obvious choice. I think he's a good manager, he just can't change games, hence why we only have 2 points from losing positions. I thought we were great first half, we just looked lethargic 2nd half, which is why Spurs got the upper hand. Dobbin, Beto, and Chermiti changed the game.
