Dieter Hecking has warned his Wolfsburg side that they may be powerless to combat Nani in tonight's Europa League clash with Sporting Lisbon.

The Manchester United loanee scored four times in five Champions League appearances - including a memorable strike at home to Maribor - as the Portuguese side finished behind Chelsea and Schalke 04 in Group G.

"We expect a very tough opponent – Sporting played in the Champions League so this is going to be a tough task," Hecking told UEFA.com ahead of tonight's clash at the Volkswagen Arena.

"We know the quality of Nani and you can't stop him all the time. He can win a match in a flash."

The Germans finished second behind Everton in the Europa League group stages.
