Well, if you cannot imagine Spurs finishing above Chelski ...I still canWhat if? I don't think prem clubs should be able to loan players to other prem clubs full stop.
Your imaginary scenario wasn't what I was advocating,
My point was purely that plenty of players have moved between the clubs in the past without it being the end of the world. This is a point of fact, not an opinion.
But the rivalry between the 2 clubs is not imaginary and in such cases, neither of the clubs wants to help a close rival become better. And I don't think right now Chelksi thinks it's just an "imagination" that Spurs could be a close competitor for the top 4 spots.
