But it's not about different jobs. It's getting less money to do the same thing. For say Danny Rose -- a 5 year deal at Spurs gets him roughly £16M. After tax let's say he's taking home £9M. Is that enough to look after him and his wife, children, parents, brothers and sisters, wife's family etc for the 50 or so years after he finishes playing, after which he has no idea if he'll earn any more money? Probably, yeah, if he's smart with it. But if he moved to Man Utd to do the exact same job for a bigger club in front of bigger crowds with more chances to win tropihes, that number would double to £32M. Sure, he likes Spurs a lot. But he looks round and sees players doing a worse job than him, but earning millions more. Why on earth would he not push to leave for Man Utd?
