The 2011-12 Champions League campaign is nearing its final stages, as the remaining four teams contest the second legs of their semi-final ties.
On Tuesday, reigning champions Barcelona lock horns with Premier League representatives Chelsea as they attempt to overturn a 1-0 defeat from the first leg.
In the other semi a day later, La Liga leaders Real Madrid host Bayern Munich at the Santiago Bernabeu. The Bundesliga giants recorded a hard-fought 2-1 win at the Allianz Arena last week and they can expect to face an onslaught from Jose Mourinho's men in the Spanish capital.
Once again, Goal.com's experts and correspondents will be on hand to provide you with in-depth coverage and analysis, and here is what they think may unfold on Tuesday and Wednesday.
BEN HAYWARD SAYS ...
Barcelona are looking vulnerable after losing back-to-back fixtures for the first time since 2009, but the Catalans remain a force to be reckoned with at Camp Nou.
Pep Guardiola's men will be desperate to return to winning ways after the disappointment of losing the Clasico - and probably La Liga - to Real Madrid on Saturday, so expect a reaction from the European champions in this match.
Chelsea rode their luck in the first leg and although the Blues defended well, I simply cannot see them stopping Barca at Camp Nou.
CLARK WHITNEY SAYS ...
A very, very difficult match to call, one that could go in either direction. However, the Spanish side's record at home is outstanding, while the visitors' away form is anything but.
Madrid triumphed in the weekend Clasico at Camp Nou, and they will be bolstered by the result.
A 3-2 victory for the hosts - which would send the Bavarians through on away goals - is entirely possible, but more likely than not it will be 3-1, and Bayern will live to regret not taking more of their chances in the first leg.
