This will be the picture after the second game. Unhappy and exhausted Chelsea players and Drogba who says you are always in my heart to Chelsea supporters.
I computed and compared both teams in a special software calculating 2810 parameters in 3 hours using all cpu's of the computer. The result is that Galatasaray is 3.83 times stronger than Chelsea.
Good luck. Galatasaray is way stronger side. First game at TT Arena 2-0 (Burak Yılmaz, Nordin Amrabat) Second game at Stamford Bridge 1-3 (Juan Mata, Bruma, Aurélien Chedjou, Wesley Sneijder)
