Chelsea have been told that alongside Man City and Liverpool, Paris Saint-Germain and Lionel Messi could indeed end up being their biggest threat to the Champions League crown due to the firepower Mauricio Pochettino has at his disposal.
The Blues aim to kick off their knockout campaign on the right foot when Lille come to town on Tuesday night for the first leg of their Round of 16 tie.
Whilst the two clubs battle it out under the lights at Stamford Bridge, all of Man City, Liverpool and PSG amongst others will be watching keenly to see how the reigning European champions fare against the so-called underdogs in this situation.
