Barcelona face a huge task in Tuesday night's Champions League last-16 clash with AC Milan as they aim to become the first team ever to overcome a 2-0 first-leg deficit since the competition's format changed in 1992.
The Camp Nou is expected to host a thrilling encounter as Barcelona, who collapsed at the San Siro three weeks ago, look to advance through to the quarter-finals in a bid to claim their fifth Champions League title.
