Norwich City might be on the up but Daniel Farke is still in the market for a new centre-back in January.

Farke made it clear after the summer window had closed he wanted reinforcements, following the departures of Ben Godfrey and Timm Klose.

City opted not to roll the dice but Christoph Zimmermann’s calf injury left Grant Hanley and Ben Gibson as the only fit centre-backs in recent games. Zimmermann returns to the mix for Tuesday’s Championship duel against Millwall, but Farke knows injury or suspension would still leave him light. Midfielder Jacob Sorensen is also set to continue as an emergency left back with Xavi Quintilla (hip) sidelined.

“I am happy with the squad and the players, and we have players who can operate in different roles, but it doesn’t take away that in a couple of positions we are a bit thin,” said Farke. “We have to closely look at the central defensive position for January. The lads playing right now are doing fantastically well, and also Christoph is back so we have another option, but the games come thick and fast.

“Hopefully no injuries to those three. It is definitely a position we have to have an eye on in January.

“The same at left-back. Max Aarons and Bali Mumba can both play there, even though they are right-footed, and Jacob has proved he can fulfil the role but he is not a natural full-back.”

Sorensen conceded a penalty at Bristol City, after his first half assist for Teemu Pukki, but Farke felt the Dane was hard done by.

“It was unlucky the clearance went back towards him when he is on the floor,” he said. “He tried to put his body on the line.

“It looked a bit clumsy but I am not sure it was a penalty. We know he is not a natural full back who runs up and down the line.

“But he can make smart passes and be solid.”
