Ralls and particularly Gunnarsson had very good seasons last year but i still contest that they are both very technically limited.
I'll put my neck on the line and say that Loic will very quickly cement his starting place in the middle of the park.
I know you tube videos can be very deceiving but you can see enough on there to suggest that he is far more technically proficient than Ralls and Gunnarsson.
His body position when receiving the ball will put the team on the front foot far more quickly than we're accustomed to.
