Like the respective supporters of their Liverpool, Manchester City and Arsenal sides, they were no doubt watching from behind their sofas as they saw key players pick up injuries while training and playing for their international teams.
It was the last thing that the managers of the Premier League's current top three needed.
As well as the title, the trio have other competitions to navigate during what could prove to be a make-or-break month of fixtures that begins this Sunday when Liverpool host Brighton before City and Arsenal go head-to-head at the Etihad.
And while Jurgen Klopp's second-placed Reds would seemingly have a better run of fixtures than their title rivals, on paper at least, of the three teams they have the most injury worries, which has been the case for most of the campaign.

So ahead of this weekend's return to action, we take a look at the latest from the treatment rooms at Liverpool, City and Arsenal....
Liverpool
The Reds already had fitness concerns over nine players going into the international break.
But while Luis Diaz, Cody Gakpo and Ibrahima Konate all came through unscathed after playing for their countries, Andy Robertson was not so lucky.
The Scotland skipper was forced off 37 minutes into the 1-0 home defeat to Northern Ireland, for whom Robertson's Liverpool team-mate Conor Bradley scored the winner with his first international goal.
Long-term injury victims Thiago Alcantara, Joel Matip and Ben Doak make up the rest of the 10 players the Reds currently have concerns over.
Manchester City
While City do not have as many injuries as Liverpool, they have picked up two big ones over the past week.
Matheus Nunes, meanwhile, returned from injury to play for Portugal last week, while fears that Erling Haaland had sustained an injury while training for Norway were swiftly squashed
Arsenal
Bukayo Saka, arguably Arsenal's most important player, handed Arteta a major scare when he was withdrawn from the England squad before their friendlies with Brazil and Belgium.
