Bayern Munich midfielder Javi Martinez has demanded caution from his team-mates ahead of the clash against Valencia on Tuesday, and is expecting a tough encounter at Mestalla.
The Bavarians defeated Mauricio Pellegrino's men 2-1 on matchday one of this season's Champions League, but the versatile Spaniard is adamant that they will have a harder time in his homeland.
"It is a difficult ground for a visiting team," the 24-year-old explained to the club's official website.
"The home fans support their team strongly, it is a compact stadium. I like it a lot, I enjoy playing there."
The hosts are undefeated at Mestalla so far this term, but Martinez has set sights on breaking their unbeaten run.
"I played the  Copa del Rey final there with Athletic Bilbao. I am looking forward to it and of course hope they get dealt the first home defeat [of this season]."
The Spain international went on to praise Che forward Roberto Soldado and singled him out as the opposition's main threat.
"He is a very agile striker, who moves well and can score a goal any time. He scored a lot of goals already. I think that he is the soul of Valencia," Martinez concluded.
Kick-off at Mestalla is scheduled at 19:45GMT.
