Borussia Dortmund goalkeeper Gregor Kobel believes Manchester City's Erling Haaland will be "very motivated" against his former club in the Champions League.
The Norway international moved to the Premier League champions for a £51.2million fee in the transfer market, quickly adjusting to life in England with three goals in three top-flight appearances.
City's star striker will be looking to transfer that form onto the continental stage when the Champions League begins next month, the start of a frantic period with the six group games condensed into a nine-week period due to the World Cup.
Drawn alongside former employers Dortmund, as well as Sevilla and Copenhagen, Haaland will have an immediate opportunity to bite the hand that used to feed him – and Kobel warned he will "definitely" perform.
"A small advantage? I think it's the same for Erling Haaland as it is for me," he said.
"So, I'm sure he knows me very well, I know him relatively well. I'm sure he will come back very, very motivated.
"And he will definitely perform well – it's always the case against your old club. But as I said, we will make it as difficult as possible for him and we want to win these games."
Haaland has a stellar record in the competition, netting 23 goals from his time with Dortmund and Salzburg for an average of 1.42 goals per game.
City have won each of their past eight Champions League home games against German opponents, meanwhile, scoring a combined 39 goals and conceding nine.
