Both Chelsea and Atletico Madrid have committed the most fouls in the Champions League this season (153). Expect tonight to be high-paced.
Atletico Madrid midfielder Gabi has won more tackles (32) than any other Champions League player this term.
Chelsea have reached the Champions League semi-finals in 7 of the last 11 seasons. An outstanding record.
Chelsea players on a booking: David Luiz, Frank Lampard, John Obi Mikel and Willian. A yellow card tonight will mean they miss the 2nd leg.
Atletico Madrid players on a booking: Emiliano Insua, Koke, Juanfran and Gabi.
