The last-16 of the UEFA Champions League has seen positive results for the Premier League clubs so far but Chelsea face a huge test when they host Barcelona in a first-leg Stamford Bridge clash.
The Blues paid a big price for finishing runners-up in their group by drawing the runaway Spanish league leaders but will still be hopeful they can build a first leg advantage on home soil.
Barca are set to field a team of stars including Lionel Messi and Luis Suarez but will be without January signing Phillipe Coutinho who is cup-tied.
