Ruud Gullit has expressed doubt on his suitability also:
"Hope I am wrong, I really do, but Higuain is an old-fashioned striker who needs crosses and, if he plays up front all the time, he will not see many balls there.
So they don’t need a player up there who is a target man, because Chelsea don’t use one and, under Sarri, they never do".
Obviously Gullit is almost always wrong, so this is worrying, but surely the question should have been, if they "never do" under Sarri, and he's so old-fashioned, who the fuck was it that scored a record 36 goals in one season for Napoli under Sarri?
