Yes he didn't have a particularly great impact in those 30 minutes, but that's not my point. He's been good for the majority of the season, so to say he shouldn't start over someone whose been poor for 4-5 matches now because he had a poor impact as a substitute seems a little odd. Not to mention the fact if he starts then we can have our front 4 all in their natural positions rather than the nonsense of Silva/KdB as wingers.
Fernando coming on for Silva was the right call? Perhaps if we wanted to hang on for the draw, which is what the last 10 minutes turned into after that substitution - but why should we be wanting to hang onto a draw against West Ham? This is a team that got destroyed by Newcastle just last week - a point is simply not a good result, we needed a win & I think you'd struggle to say we're more likely to get the win with Fernando on the pitch in place of Silva regardless of how he'd played.
Think you're misinterpreting my post, Kelechi came on & had a positive impact yes - and whenever he has come on he's almost invariably had a positive impact correct? I'm saying the manager did the right thing bringing him on for 30 minutes, whereas in the past he's given him 2-3 minutes which is next to pointless really - my point was that he should be doing what he did today more in the future, rather than reverting back to giving him 2-3 minutes which wouldn't surprise anyone if it happened.
