Juan Roman Riquelme admits that his last encounter Arsenal gave him one of the "saddest memories" of his career.

The Argentina star is back in north London this weekend with Boca Juniors, five years after he was part of the Villarreal side that took on the Gunners for a place in the Champions League Final.

Kolo Toure's goal gave Arsène Wenger's side a slender advantage at Highbury but Riquelme looked like rubbing that out when the Spanish side were awarded a late penalty in the second leg at El Madrigal.

Every Arsenal fan knows the rest: Jens Lehmann plunged to his left to save the Argentine's spot kick and Wenger's men went to Paris.

"It was one of the saddest memories of my career and one I will always remember," reflected Riquelme at a press conference ahead of the Emirates Cup.

"I thought we were stronger than Arsenal and deserved to play in the Final. We were quite unlucky, I missed a penalty and Arsenal managed to get to the Final."

The personnel in Wenger's team has changed considerably since that 2006 showdown but Riquelme still rates them highly.

"I think Arsenal are the most attractive team in the Premier League," he said. "They like to combine all the time. Whoever loves football loves Barcelona and Arsenal because they are the best footballing teams in the world.

"It’s a different match now. We have a lot of players that have grown up at Boca and it is going to be a great experience for them."
