The Spanish champions have commissioned a report over the viability of both projects with the objective to increase the capacity of their home ground to 105,000.
Although progress was made at a meeting on Monday, the Barca directors will not announce their preferred option until early in 2014.
Board spokesman Toni Freixa explained on the club’s official website it had two choices: “The construction of a new stadium on the land on Diagonal, property which belongs to the University of Barcelona, or a profound remodelling project that would constitute a new stadium keeping the current structure of the Camp Nou.”
The Nou Camp is already the largest ground in Europe with a capacity of 99,354.
