Do you really believe that if we sold Kane we would replace him with someone of jansens level?
I love Bobby Soldado. He was the last really big pre-Kane striker signing we had. But he was, unfortunately, total crap, although a trier.
And before him? Counting backwards - Adebayor, Crouch, Gudjohnsen on loan, Defoe (again), Keane (again), Pavlyuchenko, Bent, Fraizer Campbell on loan.
Yes, I think we would replace him with someone of Janssen's level. Not because that's what we want to do, but because we tend to shop for top strikers that cost too much in wages for our dear leader to sanction, fail, and then sign alternatives that are highly-priced anywayin terms of transfer fees, but well within our wage range.
Sadly, that usually means they're crap or coming off the back of an overperforming season, if that lot is anything to go by. We could (and did) have countless DoFs in charge, from Arnesen to Comolli to Baldini to now Paratici, but the same constant remains dooming everything - the man up top. They could recommend the next Messi to replace Kane, but we are likelier to cheap out on him and buy the next Vincent Janssen instead.
Just like Janssen himself, actually - if I recall, Poch didn't want him. His first choice was Batshuayi, who, while not a lot better, still had a better career in English football than Janssen did.
