To be fair I see them as a bigger club than City or Chelsea

If you look at the list of honours won Spurs are joint 5th, above City and only one below Chelsea who would have been way down the list before Abramovich and his billions. They were also the first British side to do the double, and the first to win a European Trophy I think.
But still it's been years since they were a successful side to it must be annoying them that plucky little Leicester are denying them their chance to possibly win the league for the first time in most of their lifetimes!
