Chelsea suffered a major setback on Tuesday night with Cole Palmer and Joao Pedro unavailable for their huge clash against Brighton.
But followers of Marc Cucurella's barber would have been aware of the team news hours before Liam Rosenior confirmed his starting eleven for the Premier League contest.
A post from X account @Rileyeagles on Tuesday read: 'Palmer and Joao Pedro both injured tonight. There's your exclusive' before tagging a number of high profile Fantasy Premier League accounts.
He shared a subtweet with a picture of the back of Spanish full back Cucurella's head, along with an electric razor.
Palmer is missing the game with a hamstring injury, despite playing the full game against Manchester United over the weekend. Pedro missed the defeat to the Red Devils on Saturday.
The latest leak comes after Rosenior confirmed last month that a mole who had been leaking team news had been identified - with starting lineups for both European games against PSG revealed to the media beforehand.
Daily Mail Sport understands the leaks on those occasions did not come directly from a player and is regarded as external by Rosenior and Chelsea.
‘We know (who it is),’ Rosenior told us at his pre-Everton press conference. ‘It's not come from any place of malicious intent to me or to the team. We know where it's come from and we've dealt with the situation.’
When asked directly, Chelsea did not name the mole.
The Blues are in disarray with the club facing the prospect of missing out on Champions League football next season. They entered Tuesday's contest 10 points off fourth-placed Aston Villa.
There is also seemingly discontent in the ranks, with Enzo Fernandez telling an Argentine streamer over the international break that he would like to live in Madrid.
The midfielder has been linked with a switch to Spanish giants Real Madrid this summer.
Rosenior gave Fernandez a two-match ban for his comments.
