The Blues entertain arch-rivals Arsenal at the Bridge on Sunday, fresh from an impressive 2-0 victory at Burnley and after the midweek hosting of Barcelona in the Champions League.
That win at Turf Moor was all the more impressive because, yet again, it was achieved without talisman Cole Palmer.
His injury lay-off has been extended by another fortnight after he fractured his little toe on the bedroom door while heading to the loo in the middle of the night.
It has echoes of an unfortunate incident involving Chelsea keeper Dave Beasant more than 30 years ago.
Standing barefoot in his kitchen, making a sandwich, he dropped a bottle of Heinz salad cream on his foot… and severed the tendon in his big toe.
He went on to miss eight weeks of matches in 1993, and had to put up with constant mayonnaise-themed ribbing from opposition fans for years afterwards.
The Blues’ victory in Lancashire on Saturday was a slightly nervy encounter, right up until the time Enzo Fernandez scored a second goal to allow everyone to relax.
It followed Pedro Neto’s flying header in the 36th minute after Jamie Gittens, who seems finally to be settling into a dependable rhythm, sent over the perfect cross.
But the man of the match, and arguably the most improved player in the Chelsea ranks this season, was Tosin.
The defender, only really getting his big break because of Levi Colwill’s long-term absence, is cool, calm and collected, playing with a positivity that young hopefuls in the youth and development teams would do well to study.
How will Chelsea fare against the Gunners?
The head-to-head record is mixed at the Bridge, but the Blues are generally in good spirit in the Premier League, and genuinely fancy their chances against the table-toppers.
