Apologies, I worded it badly. As in, the Twitter source is fake, but at the same time, I was wondering if Sky Sports Germany did say something. I personally have no clue, but I know some on here follow different sources. People here also seem to have some knowledge regarding the reliability of different Twitter accounts, but I don't, so it helps me distinguish fact from fiction. I don't use Twitter outside of transfer rumours this season since there are no reports otherwise ;).
Apparently, Mahrez has been aware of the offer for well over a month, and it's still unclear whether he is interested. I wonder how likely it is...
