It could have been Sorba Thomas at Huddersfield as well. Tan Kesler was at the QPR v Huddersfield match on Saturday. I think he was there watching a potential new signing. Willock or Thomas.
Surely if we're close to signing a player then the time to be watching him play for scouting purposes would be long gone. And if we're trying to keep it secret, then being pictured at his game would be a bad idea.
That said, if we are focusing on QPR and Huddersfield, I keep wondering about Ilias Chair. His name was quietly mentioned a few times in the summer. He probably doesn't fit the right-sided thing, and it's maybe not realistic anyway, but then neither was Carvalho. The fact that I've seen his name mentioned a few times over a period of time despite him not being what you'd think of as a realistic target, is what intrigues me about him.
