After the construction was complete there was no further room for expansion at Les Corts. Back-to-back La Liga titles in 1948 and 1949 and the signing of László Kubala in June 1950, who would later go on to score 196 goals in 256 matches, drew larger crowds to the games. The club began to make plans for a new stadium. The building of Camp Nou commenced on 28 March 1954, before a crowd of 60,000 Barça fans. The first stone of the future stadium was laid in place under the auspices of Governor Felipe Acedo Colunga and with the blessing of Archbishop of Barcelona Gregorio Modrego. Construction took three years and ended on 24 September 1957 with a final cost of 288 million pesetas, 336% over budget. [SEP] Knowledge 2: La Liga
