There has understandably been lots of attention directed towards what Mauricio Pochettino needs to do in order to create a massive turnaround at Chelsea. Which players he needs to sign, the masses that are required to move on and the sheer volume of work at hand.
Nothing is a certainty heading into a summer that promises to be one of the most unpredictable but also important in the short-term history of the club. Get things right and there is cautious hope that a quick return to the top tables of European football is in order. Get it wrong and it poses Pochettino a potential existential threat for the future.
There is more than just plenty of sales to make, here. The 51-year-old's ethos of total buy-in will be one that could grate with members of a disjointed, unorganised and largely demotivated group. Finding the characters and a family-like chemistry to combine with his elite level tactical acumen are also key.
