The Blues returned to winning ways with a 2-1 victory over the Croatian side at Stamford Bridge.
Goals from Raheem Sterling and the debuting Denis Zakaria helped turn things around after they conceded early.
However, the night ended on as sour note as it finished. Ben Chilwell was forced off with minutes to go with what looked like a hamstring injury.
The England international was spotted leaving the ground on crutches, throwing his World Cup chances into real danger.
It seems as though things may have even unnoticeably gotten even worse for the club.
Azpilicueta off injured
Azpilicueta was spotted struggling as he left the pitch after the full-time whistle, potentially throwing another injury issue Graham Potter’s way.
He already had Wesley Fofana and Reece James on the treatment table in terms of defenders, with Mateo Kovacic, N’golo Kante and Kepa Arrizabalaga already ruled out of yesterday’s game.
An injury to the Spain international would see the Blues really struggling for options ahead of the huge London derby with Arsenal.
With the danger of the table toppers’ Gabriel Martinelli, the club will need to come up with a solution before Sunday’s meeting at Stamford Bridge.
It is likely that Ruben Loftus-Cheek will be called upon for the task, with his attacking impotence potentially able to force the Brazilian to a position that he can not be so impactful from.
With there being just two league games until the season breaks for the World Cup, Potter will just be hoping he survives the challenging fixtures without any more serious injuries, especially among the already strung-together defence.
