If i was him id take a short term deal with matchroom to see how gbp pans out then sign for them if gbp goes well.
Matchroom's sky card is the most over hyped card in a while its fairly poor if you break it down. Think I'd rather watch Nick Compton and England bat out for a draw against New Zealand.
Camacho-Clarke and this fight now are the two most competitive and interesting fights on the card, but the Camacho fight will be after the main event and most in the arena will not stick around to see it. Should have had it on earlier and shown us highlights if there is a few early stoppages with the televised fights
