Juan Ignacio Martinez: 'Playing Barcelona is like racing against Usain Bolt'

Real Valladolid coach Juan Ignacio Martinez has compared playing Barcelona to racing against Usain Bolt.

His side travel to Camp Nou without a victory in four matches, while Barca have won every La Liga game so far this season.

"These games are marked in the calendar with a lot of excitement," he told reporters.

"Things have been very difficult. I don't want to be pessimistic but this is like going to the Olympics to face Usain Bolt. You have to face the challenge.

"We're a team that has to try things. We must express our personality with the ball, although it will be difficult with the pressure they put you under."

Valladolid take on Barca at 9pm this evening.
