Gary Cahill claimed that referee Andre Marriner missed a foul that could be seen from the moon after Swansea City held Chelsea to a 2-2 draw in a thrilling and controversial match at the Liberty Stadium.
Chelsea led after 18 minutes through Diego Costa but Swansea turned the match on its head in the second half, with Gylfi Sigurdsson winning and scoring a penalty and Leroy Fer dispossessing Cahill to put the hosts in front.
Fer appeared to make contact with the back of Cahill's legs twice before stealing the ball, but Marriner waved away Chelsea's protests and only Costa's 81st-minute overhead kick salvaged a draw for the Blues.
