Theres no way i would ever want Villa to move to the NEC as its away from the clubs roots and on the edge of the city but there's a huge difference in revenue between a new 55,000 stadium there with all the infastructure you could build similar to what Man City are doing and simply redeveloping Villa Park to 55,000
Like i said though, i would never want Villa to move as far away as the NEC, a new stadium on the site close to the new HS2 terminal as mentioned in other threads before however i would be in favour of as it could be the difference in taking our club to the next level and helping us compete with the elite clubs
