José Mourinho offered a measured assessment of Yan Diomande following the winger's first start for Real Madrid — acknowledging his "incredible potential" while making clear there remains "a lot to learn" for the club's record signing.

Diomande featured from the off as Real Madrid dismantled Rayo Vallecano 4-1 in LaLiga, a result that underlined the hosts' attacking firepower. Yet even amid the emphatic victory, Mourinho tempered expectations around the highly touted newcomer.

The manager's words struck a familiar balance — enthusiasm for what Diomande could become, caution about how much work still lies ahead. It is a tone Mourinho has deployed before with young talents brought into elite environments, signalling that the transition from prospect to proven performer demands patience.

For Diomande, the 4-1 scoreline will have provided a positive stage for a debut start, but Mourinho's post-match remarks serve as a reminder that first appearances are just the beginning of a longer journey at the Santiago Bernabéu.
