Barcelona will be out to sustain their seemingly unstoppable momentum towards the Primera Division title when they head to Eibar on Sunday. Head coach Luis Enrique rotated the defence away to Rayo Vallecano on Thursday, but his attack again delivered a familiar devastating performance as Lionel Messi plundered a hat-trick in the 5-1 win over relegation-battling hosts who ended the match with only nine men.Defender Dani Alves is set to return at the Ipurua stadium following a suspension, while Jordi Alba should come in again at left-back having been rested. Forward Neymar, though, will miss out because of his one-match ban so Turkey international Arda Turan is expected to fill in on the left, having come off the bench to score his first Barcelona goal with a late fifth against Rayo Vallecano.After extending their unbeaten run to a Spanish record 35 games - and with one foot already in the quarter-finals of the Champions League after a 2-0 first-leg victory at Arsenal - Barcelona look well set for another successful end to the campaign.Eibar, meanwhile, have suffered three defeats in a row, leaving them in eighth and off the pace for the European places.

Darrion Caldwell is still a good bet to hold the Bellator MMA bantamweight championship some day -- but it wont be as soon as some thought.Widely considered one of the top prospects in the entire sport, Caldwell (9-1) suffered a stunning defeat to Joe Taimanglo?(23-6-1) on Friday.
