New Porto goalkeeper Casillas was just one of several of De Gea's international teammates to comfort him during training, following the collapse of De Gea's proposed move to Real Madrid, where he was expected to replace Casillas as Los Blancos' number one. Casillas can be seen in the below video to utter a few 'Madre Mia's' during his conversation with his fellow Spanish goalkeeper.
Sergio Ramos and Jordi Alba also console the Manchester United goalkeeper.
