Enrique hopeful over Messi and Neymar

Barcelona coach Luis Enrique remains optimistic over the availability of Lionel Messi and Neymar ahead of Sunday's World Club Cup final against River Plate.

Messi is suffering from a painful renal colic issue (kidney stones), while Neymar is nursing an adductor muscle problem.

However, the duo participated in Saturday's training session, giving Enrique hope they will be fit to start in Sunday morning's encounter at International Stadium Yokohama in Japan.

"I am always optimistic," Enrique told reporters. "There is still today's training session, many hours left.

"The quality of any Barca player means they can play without being at 100 percent, they could play at 99 per cent. We will see."

He added: "To win tomorrow is very attractive for us, I see the same motivation in my players as in any other team.

"We are very excited about this trophy, it shows the best team of the season, it would be the cherry on top, it's a big objective for us."

Barcelona's bitter rivals, Real Madrid, won the 2014 Club World Cup, while Bayern Munich the competition in 2013.
