Kevin did a fab job supporting Alex last night, so I see no reason why Gorka would have been a better substitute, unless you're going for his looks to distract from mistakes.
Neil has tweeted how proud he is of Alex and his thanks to Kevin last night.
Gorka used to be my favourite pro, but his retweeting of people demanding him to have a partner makes him look bitter and unprofessional.
Graziano on the other hand has just got on with his job without complaining.
