The world's best player, Messi, is out with a thigh injury - news which Lennon greeted with a "tinge of sadness" - but there's still plenty of talent in Barcelona's line-up. Photograph: Richard Heathcote/Getty Images

In the opening quarter of the match, Celtic attempted 43 passes. In the same period, Barça attempted 231. But neither side can claim to have achieved much in the opening half.

Celtic's captain Scott Brown is sent off by referee Stephane Lannoy in the second half for a foolish swipe at Neymar, who was on the ground. Brown may not have made much contact with his opponent, but the referee considered it violent behaviour. Photograph: Richard Heathcote/Getty Images

Here's a picture of the incident - Brown just flicked his right boot in the direction of Neymar's back as he ran past him, but Neymar made a huge meal of it. Photograph: Carl Recine/Action Images

Ironically, ten-man Celtic soon have successive opportunities to take the lead - the first, a rasping shot from James Forrest, is excellently saved, then a header, from Charlie Mulgrew, goes just wide. Photograph: Nigel Roddis/Reuters
