A couple of big narrative strands dangle over the AEK Arena tonight, just begging to be tied up. Will Olympiakos become the first-ever Greek side to win a major European club trophy? Theyâll take possession of the Greatest Recent Cup Run baton from Manchester United if they do, having come back from a 4-1 first-leg home defeat against Maccabi Tel Aviv in the round of 16, and stuck six goals past upwardly mobile Aston Villa in the semis. Or can Fiorentina lift their first European pot in 63 years, since the 1961 Cup Winnersâ Cup? Theyâll extend their unbeaten run on the continent to 14 matches if they manage it, their last defeat being in last seasonâs final against West Ham. Should they go one step further this time, theyâll honour their victory to their late general manager Joe Barone, who died in March.
