I don't hate and judge Cesc because chose to change squad, but the modality. I remember the disgusting escamotage used by Barça to sign him. Do you remember the spanish media against us during the transfer windows? A player in cage, hostage of Arsenal, Puyol, Piquè and Iniesta publicly expressed the desire to have him with them, Reina and Pique with the Barça shirt during the party after the 2010 World Cup...
Hey mate, Cesc's departure to Barça caused me a pain.
I don't judge him because joined Chelsea (if Arsenal refused to re-sign him - but I have many doubts about this - he was right to join another big club like Blues) like RVP with Manchester United.
van Persie was right to have the desire of a title before the end of his career and in that time, Arsenal were not the right place to stay, especially if the alternative was Sir Alex Ferguson and Manchester United.
I "hate" (but I repeat, probably the hate isn't the proper word to use) him because a PL titles has removed him all the memories of his time with us. Since his departure, do you ever read a good words about Arsène or Arsenal from him?
After a period when I hated him with all my heart (because you can hate a person only if you loved her), now I understood his decision to leave. I understood what was frustrating to be the best striker in the World and play with Djourou, Ignasi Miquel, Jenkinson, Ramsey, Chamakh, Benayoun, Gervinho, Mannone and Andrè Santos.
Apart one or two bad aspects, my feelings for Fabregas, van Persie, Nasri are positive.
I hated Bacary Sagna and the pantomime to join City, hated Adebayor, hated Ashley Cole.
...and I would not hate Sanchez if he will decide to leave, but the modality of his departure. Laughing on the bench for me has been disgusting and a type of actions like this is miles away to be connected with a world class and winning mentality players.
I have seen Juventus, Inter, AC Milan to collapse and finish outside the top 10 for many years, but I never seen Buffon, Chiellini, Javier Zanetti or another player with the smile on his face.
