The UEFA Champions League semifinals get underway on Tuesday, Apr. 29 with Arsenal taking on Paris Saint-Germain for the second time this European campaign.

Treble watch continues for Paris Saint-Germain and Barcelona, both of whom have already collected their first trophies of the season and are perhaps the most formidable candidates

The Gunners beat PSG 2-0 in the league phase of the Champions League way back at the start of October and it was fairly comfortable for them, although PSG did hit the woodwork twice and showed glimpses of the team they have become.
