Gaizka Mendieta, formerly of Barcelona, insists that Diego SImeone's men must win if they are to have any chance of winning the title
Atletico Madrid's encounter with Barcelona represents their only chance to reel in the La Liga leaders, according to former Barca midfielder Gaizka Mendieta.
Atleti are five points behind Lionel Messi et al after Barca were held to a 1-1 draw by Las Palmas on Thursday.
The two sides will clash this weekend at Camp Nou, with Atleti looking to extend an eight-game unbeaten streak in all competitions.
And Mendieta believes the game offers perhaps Atleti's only chance to close the gap as the season progresses.
