Have not yet been impressed by Guessand, but I don’t think an off game like tonight (among off games from other players) means it’s fatal.
He had been improving and does have a bit of pedigree from Ligue 1 last season, among the league’s top forwards and player of the season at Nice.
Interestingly, he was considered a revelation last season after a long period where nobody really rated him, so I’m clinging on to the hope that it will come good!
