Arsenal await as Bayern Munich and Paris Saint-Germain contest the second leg of their Champions League semi-final tie in Germany tonight. There are huge expectations for another pulsating showdown between two of Europe’s biggest clubs after last week’s nine-goal thriller at the Parc des Princes, a modern classic that saw so much scintillating attacking football and jaw-dropping shifts in momentum as holders PSG eventually triumphed 5-4. It was the highest-scoring contest in the history of Champions League semi-finals and one of the best games in recent memory.
