Arsenal left-back Sead Kolasinac has been labelled as a 'machine' by former team-mate Dennis Aogo.

The pair played together at Schalke, with Kolasinac eventually pushing Aogo out of the side.

But the 33-year-old has only admiration for the Bosnia international.

Speaking exclusively to Goal, Aogo said: "I have to admit that Sead Kolasinac took a brutal step that year and regularly destroyed his opponents.

"Sead marched up and down with incredible power on the left side. I didn't have even a small chance in the direct duel. I have to be so honest, even if I didn't want to admit it at first. I don't remember a duel that Sead didn't win at the time, as a direct competitor I was almost a fan of him.

"In addition, he was never injured, sometimes he even played with torn fibres or other diagnoses. I thought to myself: 'Is he still human?' He could push the pain away like a machine. It was hard to believe."
