Jurgen Klopp's long-time advisor, who recently signed a contract with the Reds until 2022, upholds the German's priority of exposing talented players to first-team football regardless of their age
Grujic was signed for £5.1 million from Red Star Belgrade in January and despite not making his first-team debut during the latter part of the season, is still held in high regard by the coaching staff on Merseyside.
"We are very, very optimistic. Not [only] since Wednesday, because we knew him before of course," Krawietz told LFCTV in reference to the 5-0 win over Fleetwood Town on Wednesday, where Grujic opened the scoring.
"He has had a good start and this is the point from where we can start to work with him and develop improvement with him. He has the possibility to play in different positions in midfield.
"He is a young player; he still has to adapt to the Premier League and our style of play. We know you need strong players and tall players - a mixture for Premier League football. He has every possibility to adapt quickly."
