An unexpected first defeat for Barcelona in Glasgow on Wednesday evening, Tito Vilanova's side losing 2-1 to Celtic. The Scots used the same tactics as two weeks ago in the Nou Camp, sitting back to defend and looking to score on the breakaway. And although Alexis had a shot blocked and Messi fired an effort over the crossbar in the opening minutes, once again Neil Lennon's side took the lead, Wanyama getting above Alba on the far post to head Mulgrew'a corner past Valdés. Later in the first half Messi shot against the bar and Alexis headed against the post, and after the restart Forster did well to keep out the two forwards once again. However with ten minutes to go Xavi failed to cut out a long clearance by the keeper, and young substitute Watt ran on to make it two. Soon afterwards Mascherano was lucky to be let off a possible red card when he stopped Watts as he threatened to score again, and although Messi finally got the ball in the net after Forster could only push out a shot from Pedro, it came to late to save the day. Barça stay top of group G however, but Celtic are now only two points behind them in the table.
