Arsenal take on Bayern Munich tonight for the the last-16 second-leg fixture at the Emirates Stadium, as the Gunners look to overturn a 5-1 deficit from the first game. Arsene Wenger's side have a mountain to climb following a disastrous second half at the Allianz Arena. The Gunners went into the break at 1-1, Alexis Sanchez following up his own missed penalty to level the scores after Arjen Robben had given the German side the lead. The floodgates opened in the second period, however, with goals from Robert Lewandowski, Thomas Muller and a Thiago Alcantara brace leaving Arsenal's hopes in tatters. Analysis tonight provided by Graeme Souness, Kevin Kilbane and Brian Kerr. (Kick-off 7.45pm).
