In an effort to turn the Blues into winners, Graham Potter has hired the All Blacks mind coach, ilbert Enoka, who instituted a "no d***heads" policy.

Since Todd Boehly took over as owner, Chelsea has made significant investments in players, but on-field success has not yet followed, leaving them in ninth place in the Premier League.

Thomas Tuchel was fired in September, and Potter is working to establish himself as the manager who can lead Stamford Bridge to successful campaigns and championships.

Gilbert Enoka, who has had a significant impact on rugby union with New Zealand over the previous 20 years, is now moving to the London club.

Enoka, who stepped up from being mental skills coach to become leadership manager with New Zealand, will join up with Chelsea on what New Zealand said was a "short-term consultancy basis".

Potter should benefit from the new experience, since the highly regarded Enoka was a member of the All Blacks lineup that won the Rugby World Cup in 2011 and 2015.

Chelsea have spent around £600million on new players in the past two transfer windows, without their sprees having had any obviously positive effect on results, and installing a positive mindset appears to be what they are looking at achieving.

Enoka revealed in early 2017 how his famous policy functioned within the New Zealand ranks, saying: "A d***head makes everything about them.

"We look for early warning signs and wean the big egos out pretty quickly. Our motto is, 'If you can't change the people, change the people'."
