Mikel Arteta might have set the tone after the first leg at Arsenal, as he called for “something special”, but it was maybe Luis Enrique who properly set up the second leg. Despite his Paris Saint-Germain team’s impressive win on Tuesday night, he said “it’s just got started”.
While these may be words that seem general enough in European knock-outs, they touch on a deeper truth at this stage. The second legs of such ties, and especially when they're the semi-finals and so close to the club game’s greatest stage, can turn into whirlwinds.
