Dortmund - Borussia Dortmund captain is set to return to full team training again on Wednesday after a spell on the sidelines with a knee injury.

“This week I made a big step forward,” the 25-year-old said in an interview on the club’s official website. “Now I need to catch up and get fully fit. My plan is to train with the team on Wednesday. Then it will be up to the coach to decide when I play again.”

Doubtful for Matchday 4

His return would be a welcome boost for coach Jürgen Klopp, who is still without several of his key on-field leaders, including Marco Reus, Ilkay Gündogan, Jakub Blaszczykowski and Nuri Sahin, all of whom remain sidelined with injury. Hummels was non-committal as to whether he could feature in the side’s Matchday 4 encounter with 1. FSV Mainz 05 next Saturday, saying “we have to see how it works in training.”

The defender, who is hoping Dortmund “get off to a good start and win at home” in Tuesday’s UEFA Champions League group game against Arsenal, also expressed his delight at Shinji Kagawa’s comeback in a BVB shirt: “Shinji can hardly have imagined a better day. The game was a bit scrappy at the start, but the opening goal was – as the coach always says - the ‘can opener’. It forced the opposition to open up a bit and gave us more space. We used this to our advantage, played better football and picked up a deserved win.”
