Fortuna Dusseldorf coach Friedhelm Funkel praised Zak Steffen after their 1-1 draw with Hoffenheim.

Having conceded four in defeat to Bayern Munich, the on-loan Manchester City goalkeeper was back to his best on the weekend, producing two wonder saves in the second-half.

Funkel was delighted with the American's return to form - though was also eager to keep Steffen grounded.

He smiled afterwards: "I just expect Zack to make such saves.

"Of course he is an important constant in the fight for survival! But he too can improve..."

Steffen is on a season-long loan at F95.
