Every now and then, the elite tacticians can be accused of trying to be too clever for their own good. Marc Cucurella inverting not only into midfield but as a No 10 and into the front line? You sure, Enzo? You know he is a left back? OK. Whatever you say.
That only makes it all the more sweeter when it works, as it did for Maresca here to take Chelsea up to second in the Premier League before Manchester City's evening clash with Newcastle.
Cucurella was the highest player up the pitch when Tosin Adarabioyo had the ball in the Blues' back line after 37 lacklustre minutes from the visitors at Turf Moor.
