To where?
Chelsea - and, obviously - Arsenal will have vacant spots this summer, and Mauricio Pochettino has hinted that he does not expect to stay at Spurs forever.
Last season, Pep was on a steep learning curve, and, if I remember some of the coverage rightly, he was criticised for not having done better. But he watched, studied, thought and learned, and crafted a response to the circumstances in which he found himself with the tools (playing staff and support staff) to hand.
I'm not sure what will suffice to offer him a challenge next year, given that he has won the Premiership in such swashbuckling style this year.
