Maybe a league cup or something but certainly not the league or champions league which is really what he would be wanting to leave for. You guys may not like to accept it, I know Utd are a much bigger club than Spurs but in terms of actual results, they are pretty close to each other at the moment. There is not a dramatic difference on the pitch which is what matters.
Going forward, absolutely there is a much better chance. He'll have 1 year left on his career and will be 30, he has to move if he wants to wherever there is a decent chance. It's not City (yet..), but they have Haaland. This season there is absolutely a dramatic difference on the pitch already (as shown in the match between the 2), and it's only half a season with Ten Hag so far. We have some absolute world class players, who would be the best group of players Kane has ever played with without a shadow of doubt in Varane and Casemiro. And he would fit us like a glove, and every player envisions how they fit in and what impact they'd have. Kane would without a doubt would give us that bit extra to compete.
United is basically the 3rd best team in the league after a few months of ten hag and not having a striker. Been right up there with Arsenal and City since Casemiro came in. So you can be sure a striker like Kane added to United who have had a net negative as our attacking group apart from Rashford could give this team a massive lift.
Now... I don't think it'll happen ultimately, if Bayern goes for him I think Levy would take half of what United offer for him to go there. But United is really the only other option (and I'm pretty confident we'll be top 4), as i don't think he stays at Spurs when you miss out on top 4 this season. With Bayern, it just makes sense, but at the same time... They don't usually go for older players. And he may want to stay in England and compete for the Prem rather than go to Germany to just get some Bundesliga titles. And no other Premier League side is an option, so at least he could have 5 years at United going for the title with a potentially elite manager with elite resources.
