Again, when was the last time Sergio had a great performance away from home? Can you answer this question? What about his last great performance in an away game against a top team? When was that?
We have lost the games in which Segio has started away from home (Norwich, Liverpool, Wolves) bar relegation fodder Bournemouth which was quite a difficult game too and we conceded many chances there. That's an interesting fact in itself. Scoring a pen for 4:0 against Wham and 1 from many chances against Norwich doesn't make for great performances. He has scored goals against Bournemouth (relegation zone), Norwich (worst team in the league) and a pen against Wham (in a relgation battle). All those goals came in the first weeks of the campaign and when Jesus was injured.
Has Sergio scored against a good team this season?
"He hasn't scored more because he has started only 4 games". But why hasn't Sergio started more games away from home? Is it because he hasn't been particularly good in away games and doesn't help the team as much as expected? Did he play well against Liverpool or rather was one of the reasons why we lost the game because of poor finishing?
The best strikers are great not only at home but also away from home. Sergio hasn't been that great in away games for a long time now. He was fairly shit against Spurs away in the CL. He wasn't impressive against the rags in April either. Very much hope he gets better because we need his class in the CL, but there is a reason why he starts almost all games at home and rarely away from home.
Vardy has been more clincial than Sergio. City create much more chances than Leicester, so Sergio having scored at a slightly better rate than Vardi in term of goals per minutes doesn't make him better or as good as Vardy this season. Only a deluded blue would think otherwise.
