We all know Derby County are a huge attraction but it seems we may now be rivalling the Welsh National team.
There are not many times Cardif City have to open the Ninian Stand, an upper tier in their 33,280 capacity stadium but this is what will happen on Saturday.
It can't be said that it is not all the work of loyal travelling Rams fans though, as Cardiff make an offer of a free ticket to any Blue Birds renewing their season ticket, or purchasing a new one.
Cardiff rarely attract more than 20,000 to the Cardiff City stadium but the offer and the visit of the Rams, who sit just two places and five point behind the Rams.
A must win game for both teams and a super atmoshphere as well, what more could you ask?
