The Latest: Barca-Bayern, another classic Euro game

BARCELONA, Spain (AP) — 7:15 p.m. (Spanish time)

Will the Barcelona crowd that once adored Pep Guardiola turn on him tonight? Can Lionel Messi hopscotch Cristiano Ronaldo as the Champions League top scorer?

So many questions. You'll find the answers here over the next hours from the mouth-watering Champions League semifinal of Barcelona vs. Bayern Munich, playing the first of two legs for a place in the June 6 final in Berlin.

At Barcelona, Guardiola delivered trophies faster than pizza. A heap of them, including six Spanish league titles, as a player who came up through the club's youth system. And 14 more in a golden spell as coach from 2008-2012. Then he crossed to the dark side. Bayern's manager since June 2013 makes his first return to Barcelona's Camp Nou tonight. Will Europe's biggest stadium snarl or welcome him back?

Football's greatest rivals — Messi and Ronaldo — were tied on a record 75 Champions League goals each until the Real Madrid forward scored his 76th against Juventus in the other semifinal first leg on Tuesday night. Juventus won 2-1, a narrow advantage to nurse in the second leg next Wednesday.

Anything Ronaldo can do, Messi can do better?

Kick off is 90 minutes away.
