But their hopes of progression were brutally quashed by the European champions. Khvicha Kvaratskhelia beat Mamadou Sarr, the 20-year-old Champions League debutant, with uninhibited ease to slot the opener home after just six minutes to put the result effectively beyond doubt. Bradley Barcola followed up with a goal of his own just eight minutes later, leaving Chelsea trailing by five at half-time. The introduction of Josh Acheampong at half-time did little to inspire the listless Blues and Senny Mayulu smashed a third beyond Robert Sancehz midway through the second period.
