Turkish journalist, Serdar Ali Çelikler: You saw the physiques of some players at Aston Villa, right? Are they taking extra muscle boosters in the Premier League or what, they all look like giants. A team that's way superior to you physically.
You'd be scared to even pass by Tyrone Mings. You wouldn't sleep for 3 days. Just imagine seeing Onana in the locker room. You'd break out in cold sores everywhere, your sleep would vanish. https://x.com/fenerkolikorg/status/2014544153766482420
I took this as more of a slur on the Premier League and the dubious ingestion of banned substances in sport ...
... maybe naively not linking to the two mentioned players.
Yes, the mention of muscle boosters might have been a clue as to what he was referring.
