Manchester United's Ryan Giggs has labeled Inter Milan defender Javier Zanetti his toughest ever opponent.

The 38-year old Welshman has played against many during his extensive career but feels that the Argentine, also 38, has been the hardest man to take on.

"The most difficult opponent to play against was Javier Zanetti," Giggs told Gazzetta dello Sport.

"I faced Zanetti for the first time in the Champions League quarter-finals in 1999, he was the right-back and I was on the left.

"He impressed with his qualities, his speed, power, intelligence and expertise.

"I played against him twice more and he was my most difficult opponent, a complete player."
