Sañudo played football as a child in his hometown Torrelavega, and formed a team Deportivo La Paz to play in local tournaments in his area. Studying to be a lawyer, Sañudo was prolific in high school and college tournaments which prompted him to sign with Alavés in 1931. After his stint with Alavés, he moved to Valladolid to finish his last years of study in law, and was then signed by Valladolid where he helped them achieve promotion to the Segunda División.[1]
