I wonder if Tottenham have a Plan B in case of Kane's departure this summer. Because Bayern Munich still seem determined to sign him. Some rumours say that Tottenham might go for Lukaku but I don't feel like the player would accept any offer from them. He is favouring Inter much more than any team interested these days.
But Tottenham still should be able to find a decent striker to fill Kane's place. They don't need to sign a world star like him as well. Because even though they have one now they still can't win any title. They need to focus on improving their performance as a team and then they can be more successful even with just a decent level striker.
Tottenham won't qualify for the UCL next season I think because that makes it difficult for them to find a quality or world-class striker and also because that makes it even more difficult for them to keep Kane.
In fact, I think Tottenham should be able to find a striker who is comparable to Kane or more if Kane chooses to leave in order to be able to improve the team's performance so that they can return to compete at the top of the Premier League.
