The squad are staying at a hotel in a built-up part of Rostov, where they due to play their second Group F game against South Korea tonight at 1:00am AEST.

As night fell, a huge crowd of El Tri fanatics gathered outside the hotel, some arriving in a brightly-painted, flag-bearing bus.

They made a right old racket, singing songs that called the team to come down to meet them while a mariachi band played at full blast.

Their wish was granted shortly before 10:00pm local time, when they were greeted at the front door by veteran defender Rafael Marquez and a number of his teammates.

The players briefly joined in the singing and dancing, until the 39 year-old Marquez thanked them greatly for their passionate support but asked them to leave it there.

It was all smiles, and rightly so - there's a  tremendous sudden feel-good factor around the squad after their heroics against Germany in their opening match.

"They're unbelievable, unconditional - the fans and team together, with the same goal!" said the team's Twitter account, adding, "It's time to rest for tomorrow."


Mexico are top of the pops in Group F after their excellent 1-0 win over the holders, level with Sweden, who beat South Korea by the same scoreline.
