I think he would have gotten one as there would be special dispensation taken into account including a possible wage increase if he returned from loan which goes towards the permit.
I think the weirdest situation ive seen was with Peneranda (sp) who Watford signed and loaned to their sister club and only got a permit last Nov I think...
In all seriousness I think the French and German leagues are two interesting specimens following the Leipzig model...
Depends if he truly believed he would only be at porto for 1 season then onto madrid...
I only heard of him after Nymzee mentioned him in a post at the start of the season I think...he looked to me like a player who had a huge amount of attributes.
I liked Mina before we signed him but may have been swayed due to reading about him when barca were first linked a couple of years back...he seems to have a lot of positive attributes that suit our league. However, he's not been fit or had a run of games and I think although hes on a long term deal we really should be expecting a lot more from him.
As
@bicycleheader posted, I wouldn't even be bothered if we punted all our centre backs and brought new ones in. Perhaps 1 youth prospect as 4th choice (Feeney) a young but first team experienced 3rd choice (Holgate) and go out and buy 2 starters unless Mina is still considered a first choice player after the 27mil fee.
A lot of talk about striking options and centre midfield but the right back and centre back options just aren't there...
