Hello and welcome to LIVE text commentary of the Champions League last 16, second-leg clash between Barcelona and Arsenal at the Nou Camp. The Gunners face a mammoth task to turn the tie around after losing the first leg 2-0 at Emirates Stadium. The Catalans boast one of the finest attacking triumvirates in history and it would surely be one of the greatest comebacks ever if Arsene Wenger masterminds something special tonight. Arsenal’s season is in danger of imploding once again and a positive display – even in the face of probable elimination - is vital if they are to get back on track. Kick off 19.45 GMT.
