Jonathan Viera wants his Rayo Vallecano side to have belief when they face Barcelona this weekend.
The Franjirrojos face the Blaugrana in Madrid on Saturday, and the attacking midfielder has urged his team to go into the match with confidence.
“I believe my team can beat anyone,” he told a Press conference. “We have to be convinced that’s the case.
“We all know who we will be playing – they are probably the best in the world. But we are playing at home with our fans behind us.
“In a 90 minute game, anything is possible.
“We have to be convinced we can get a result.”
