Colombia have a 1-0 lead over Greece at half time in their World Cup encounter in Belo Horizonte.
The Colombians made the breakthrough with just five minutes on the clock when Pablo Armero popped up inside the box to scuff his shot home from 12 yards.
Greece almost responded instantly, but Panagiotis Kone could only slice his shot wide following a quick break from the former European champions.
Both sides showed little fear in going forward for the remainder of the half as James Rodriguez shot off target before Jose Holebas headed wide at the other end.
Colombia looked the more likely to score as the half drew to a close thanks to some incisive attacking play, but it was Greece who came closest when Kone's rasping drive from the edge of the area was parried away by David Ospina.
