Regarding Arda Guler and Real Madrid, I know this player was very close to Barcelona but unlike Real Madrid, they couldn't give him a good offer and they even asked him to stay in his team on loan for one season. I think Arda Guler made a good decision to accept the offer from Real Madrid because there he can have enough facilities and coaches to improve himself because as an 18y old player, these days are very much important for him and he can even stay in Real Madrid for years during his senior career.
Well for him was much better actually sign for an elite club then to go on loan. This was good for both his team where he was and for himself. Hopefully Real Madrid dosent send him on loan somewhere because he can show a lot more at Real Madrid. But its just a question how much minutes will he receive in Real Madrid this season.
