Mexico will debut against South Korea in the Olympics on the back of a friendly loss against Japan.
The CONCACAF Pre-Olympic champions will face off against the Tigers of Asia on Thursday at St. James' Park in Newcastle, kicking off the activities for Group B.
"[South] Korea is a strong rival," said Tena to the assembled press. "You see a lot of physical play in their matches. It's going to be a very disputed match."
Tena assured that the stage is set for good football to be played thanks to what he perceived as "a perfect pitch" in Newcastle.
"The stadium is beautiful. The pitch is impeccable, it's perfect to play on and the conditions are there so that both teams can give the fans a nice spectacle," said the former América manager.
Following the meeting in Newcastle, Mexico will face Gabon in Coventry on July 29.
South Korea will play its second group match against Switzerland minutes after the finish of the Mexico-Gabon game.
