FC Copenhagen coach Ariel Jacobs has urged centre-forward Andreas Cornelius not to rush into a move away.
"I would say that Cornelius primarily must confirm that he can play at a stable level over a long period for FCK, where we will not judge him over a short period of time," Jacob told Politiken.dk.
"When playing in a major European league, where there is much more competition, another player can take over his position if he drops his form. This will make it difficult for him.
"Cornelius must acquire more experience here so he can get a better base before he sooner or later switches to a club abroad."
