The interim Barcelona coach has called for the officials to “go unnoticed” during the clash with Real Madrid, asking for both sides to play the game in a sporting manner

Barcelona stand-in coach Jordi Roura has called for the referee to “go unnoticed” during his side’s clash with Real Madrid on Tuesday.

The game will be officiated by Alberto Undiano Mallecano, who also took charge of the 2011 Copa final between the two sides, and Roura is hoping he will not ignore any tough Madrid tackling.

“The numbers [with Undiano] aren’t good. We still remember that he allowed many fouls in the cup final,” he told reporters.

“We hope that their decisions do not mark the match and that they go unnoticed. Every Clasico is intense, hard. But we hope it won’t run out of hand and that it stays within the sporting limits.”

Lionel Messi has come in for criticism from certain parts of the media after allegedly insulting Madrid assistant coach Aitor Karanka, and Roura went on to defend his charge.

“Every player can improve, but looking at his numbers this season, I think the campaign by some media against Messi is out of place.”

Barcelona have conceded a number of seemingly unnecessary goals this season, and Roura was quick to assure supporters that they are working to address the issue.

“We’ve analysed the goals we’ve conceded. Sometimes the opponent just did well, other times we’ve made mistakes. We need to focus more.”

Barcelona and Real Madrid kick off at 21:00CET on Tuesday.
