In search of the 10th manager of his 12-year tenure as Chelsea owner, Roman Abramovich appears no nearer to his dream of owning a self-sustaining, crowd-pleasing football team.

Claudio Ranieri is refusing to entertain the prospect of a Premier League title challenge from Leicester City even though his side travel to Everton on Saturday as surprise leaders.

Atletico Madrid sealed their place in the last 16 of the Copa del Rey with a ninth consecutive win in all competitions thanks to Thomas Partey's solitary goal against Catalan minnows Reus on Thursday.

Jose Mourinho's sacking by Chelsea is likely to entrench his reputation as a manager who effectively guarantees short-term success, but for whom legacy-building represents an unsolvable puzzle.
