Thomas Tuchel's dismissal as Chelsea head coach this week sent shockwaves rippling through European football, with ruthless new owner Todd Boehly dropping the axe in true Roman Abramovich-fashion just 100 days after succeeding the ousted Russian at Stamford Bridge.
It was a move as surprising as it was confusing. Tuchel, who led the club to a second Champions League crown merely 16 months ago, had surely acquired enough credit in the bank to survive an early wobble this season - especially after Boehly had supplied him with a £270million war chest over the summer.
