Valencia coach Quique Sanchez Flores believes his side’s league campaign has been hindered by call-ups to the Spanish national team.

“One of the heaviest burdens we have had to bear this season is that we have become the team that provides most players for the national side,” Sanchez Flores told Sport newspaper on Friday.

“Despite suffering a host of injuries this season this team has been the basis of the national team. It obviously shows we have good players but it makes big demands on us too.”

Valencia have provided six players for the Spain squad for the upcoming Euro 2008 qualifiers against Latvia and Liechtenstein, while rivals Barcelona and Real Madrid have supplied have three and two respectively.

Sanchez Flores complained that midfielders David Silva and Miguel Angel Angulo had both been called up despite suffering from injuries.

“Silva couldn’t play for us in the last match and Angulo has got a serious muscle strain,” he said.

“I’m worried because I could see it coming. I know they are going to push them to the limit and they might not be fit when they come back here.”

Valencia are in fourth place in the Primera Liga, five points behind Sevilla and seven behind Real and Barcelona with two games left to play.
