Champions League matchday in Opta numbers

The end of the Champions League group stage is closing in, and on Tuesday the likes of Tottenham, Inter, Paris Saint-Germain and Liverpool will learn their fate.

Most eyes will be on groups B and C, with several European giants at risk of being eliminated before the knockout phase.

Liverpool hosts Napoli, with both sides - as well as PSG, which faces Red Star Belgrade - still able to go through from Group C, while Spurs travel to already-qualified Barcelona.

Mauricio Pochettino's Tottenham needs to match the result Inter manages at home to PSV Eindhoven, meaning either Spurs or the Serie A side will drop down to the Europa League at the turn of the year.
