All good but maybe I can explain so it's properly clear.
Sutton was a big signing for Chelsea in the pre-Abramovich era. He scored a lot of goals at Blackburn before he came to Chelsea and he scored plenty at Celtic after he left. The problem at Chelsea was that Sutton thrived in a team playing direct football with lots of crosses to make use of his aerial power. Chelsea's style was nothing like that at all, we had been through the Hoddle reformation and Sutton had to play alongside the likes of Zola, Poyet, Desailly, Di Matteo in a passing team. It was a complete mismatch. Chelsea needed a mobile, clever striker to knit things together (as Vialli had done previously) and that wasn't Sutton's game at all.
His confidence was knocked, he had a terrible run and could hardly score a goal (I think he managed 1 PL goal all season) but in actual fact the fans were always on his side because he tried like hell. We could see that it was a mismatch of styles and Chelsea fans in that era were old school, the glory-hunters hadn't yet arrived. If you want a more recent comparison, think Benteke at Liverpool.
So... when someone says Chris Sutton/Chelsea that is my reference. I can literally remember game after game of willing him to score. I even had a mate that decided to back him to score every game and increase his bet every time so eventually he would win and he had to give up in the end because he couldn't afford it any more.
Morata is a completely different case. He has already scored 12 goals for Chelsea for a start but the main thing is that he certainly does suit Chelsea's style of play, there is no mismatch there. He's just having a dodgy run and adapting to being the main #9 at a top team for the first time. But when you watch him there's no sense that he'll struggle to ever score a goal for Chelsea. It's more the opposite - that you know he will come good soon enough.
That's the reason I commented that calling Morata's recent performances "Chris Suttonesque" isn't right. It's just a completely bad comparison. But, as I said before, only someone that watched Sutton week after week and knows what that was actually like would probably know or care really. Which is why I should maybe have let it pass in the first place.
