WE are heading into the business end of this season's Champions League.

Manchester City are the current holders after they capped off their Treble-winning campaign with the biggest European trophy in football.

Rodri's 68th-minute strike secured the 1-0 win for Pep Guardiola's side against Inter Milan in last season's final.
