In Chelsea news, the Blues have a new Tinkerman at the helm.

Former Blues boss Claudio Ranieri – who coached at Stamford Bridge from 2000 to 2004 – earned himself the famous nickname as a manager who loved to tweak his tactics and personnel.

But now Graham Potter is following in his footsteps.

After just nine games in charge of the Blues, the 47-year-old Englishman has already started SIX different formations.

He kicked off the home game against RB Salzburg six weeks ago with a 3-5-2, before testing out a 4-2-2-2 against Crystal Palace and a 3-4-2-1 against AC Milan.

A 4-2-3-1 was then sampled in the win over Wolves, but he reverted back to a 3-4-2-1 once more for the return fixture with Milan.

The 3-4-2-1 was maintained in the 2-0 win over Aston Villa, before a 3-5-1-1 was wheeled out during the goalless draw with Brentford.

The bi-gamely 3-4-2-1 then reared its head once more against Manchester United at the weekend, but again Potter tinkered in Austria on Tuesday night as he lined up with a 3-4-1-2.

And it bared fruit as goals from Mateo Kovacic and Kai Havertz earned them a deserved 2-1 win over Salzburg – three points which booked their place in the last 16.

And despite all of these nuance tactical changes from Potter, Chelsea are still yet to lose under the former Brighton man.

It’s now nine games without defeat for Potter – who has won six and drawn three since taking over from Thomas Tuchel at the beginning of September.

And he has already had to face adversity since coming in.

Kalidou Koulibaly recently became the latest player to be ruled out of crucial games through injury – although he is expected back for the weekend.

But Potter has also had to deal with the absence of N’Golo Kante, Wesley Fofana and Reece James.

And first choice keeper Edouard Mendy was also sidelined for a period of time.

His defence has been decimated, yet they have conceded just four goals since he took charge.

Their next block of fixtures ahead of the World Cup will undoubtedly be the real litmus test for that back line.
