Speaking after yesterday's defeat to Inverness Caley Thistle, Strachan said: "My brain is scrambled at the moment, so it's gobbledegook what you're talking to me, I'm just thinking about the game. Whatever you said there, I don't know what you're talking about."

However, the player's agent Klaus Schlaude indicated that the two clubs may already have agreed a fee: "Sevilla informed us Celtic have made an offer and we know they are a big club.

"We are hoping Andreas will be allowed to leave in the next transfer window."
