The 35-year-old arrived at Old Trafford over the summer on a one year deal and has since gone on to claim 26 goals under Jose Mourinho.
Questions continue to loom over whether Zlatan will decide to activate a clause in his contract that would stretch his Man United career into 2018.
Herrera, nonetheless, was quick to emphasise the importance of having such a domineering figure present at Old Trafford.
“[Ibrahimovic] is a genius, he’s very intense because he wants to win everything, even football-tennis,” he said.
“He assumes this role of doing or saying what he likes in front of the media because he does not care; he can say that he’ll score 30 goals or is the best because he can afford to.”
Just imagine playing football tennis with Zlatan for a second. Think about how inadequate and defeated he would make you feel. I can picture it now: placing a header over the net and being met with a monstrous bicycle kick that smacks me directly on the nose. “It touched you last,” he says resoundingly, looming over my limp body with a haughty smile as blood gushes from my nose, “Zlatan is the champion once again. Come on, get up – champions do not lie on the floor.”
An unpleasant situation, yes, but without doubt the exact kind of approach that supporters crave to see from somebody leading the line at Old Trafford.
