Teams: Chelsea, Deportivo, Parma and Dortmund
I forgot Oriol Romeu, who is called with Mata to represent Spain. So, five Chelsea players to the Olympics.
I think our pre-season starts tomorrow, and I can see the following first-team players involved: Ross Turnbull, Henrique Hilario, Branislav Ivanovic, Gary Cahill (maybe injured), David Luiz, Sam Hutchinson, Paulo Ferreira, Ryan Bertrand, Oriol Romeu, Michael Essien, John Obi Mikel, Frank Lampard (maybe injured), Ramires, Josh McEachran, Kevin De Bruyne, Marko Marin, Gael Kakuta, Eden Hazard, Ulises Davila, Daniel Sturridge, Romelu Lukaku.
David Luiz, Bertrand, Romeu and Sturridge will leave in a few days for the Olympics. Youngsters like Jamal Blackman, Todd Kane, Nathaniel Chalobah or Lucas Piazon are expected to train with the first team too. I don't know anything about Yossi Benayoun.
