Be sure to tune in to Chelsea TV early to catch the introductions and the festivities and whatnot. The match itself starts at the top of the hour.

If you were hankering for a fun, weird, new lineup, today is your day. There's Cuadrado at right back (which is where he started his career), RLC and Traore getting starts, and two goalkeepers on the bench. Sadly, no sign of Kenedy, at least not according to Chelsea Twitter.
At least that's what we thought at first, but then it turned out that Traore was left back (huh?) and Cuadrado was the right wing. So, yeah.
