I do not get all this grizzling over where the players come from. Look at each player on what they can and have bought to the team. Mccarthy = one of our better players, Alcaraz = when he has played looks like he could be Jags partner for a couple of seasons, Robles = young and very good backup to Howard and Kone was unfortunate to get an injury just at the start of his Everton career. I have faith though that when he does come back he will be an important member of the squad.
As for Mcarthur if he does come in, then i am positive he can bring a lot to the team as and when he needs to. It will give players like Osman more competition which in turn should raise everyone's game.
If Bobby thinks two players from Shrewsbury/Crewe/Torquay etc can enhance our squad then i will back him and them until i see it is detrimental to our football club.
Just because people pay big bucks for foreign players, it does not equate to instant success.
