Grujic is on-loan at Hertha for the season.
He told BILD: "When we score a goal, I sometimes look to the coaching bench and realize that Pal cheers just as Jürgen does.
"Both are very passionate coaches."
Grujic continued: "They like counter-pressing and fast counterattacks.
"Both have a good sense for one-on-one talks. They feel when there is need for a word."
