Chelsea gifted Barcelona an advantage in their Champions League tie as Andreas Christensen’s error led to Lionel Messi’s equaliser. Willian had given Chelsea the lead at Stamford Bridge, while Barcelona were struggling to create clear-cut chances throughout the match. But the Premier League champions were punished for one lapse in concentration and Messi was on hand to rescue a 1-1 draw for Barca. Christensen sparked Barcelona’s equaliser with a pass across his own box towards Cesc Fabregas.
