Chelsea are keen to reunite Leandro Trossard with former Brighton boss Graham Potter if they can beat Atlético Madrid in the race for the 27-year-old's signature.
Trossard has starred for the Seagulls this season, initially under Potter's stewardship prior to Roberto De Zerbi's appointment at the AMEX Stadium.
He has netted five goals in just nine games, most notably becoming the first visiting player in 13 years to score a hat-trick at Anfield.
