Marcos Alonso's late header was enough to give Chelsea a 1-0 win at Slavia Prague in the first leg of their Europa League quarter-final on Thursday night.
The Blues put in an underwhelming performance on the night, with several squad players failing to take advantage of the playing time opportunity gifted to them by Maurizio Sarri.
The Czech league leaders, who knocked out Sevilla in the last round, were impressive in their commitment levels, and pressed Chelsea high up the pitch from the start, something which Sarri's side found difficult to adapt to.
Slavia may have shown that they deserve to be at this stage of the competition, but the Blues' quality eventually showed.
The Premier League side can take some confidence into the second leg knowing that they have never lost a European knockout tie
Even more ominous for the Czech side is that Chelsea's only home defeat in Europe since 2014 was against Paris Saint-Germain, making it just one defeat in 17 contests.
