AC Milan are watching Villarreal midfielder Sami Castillejo.

Marca says Castillejo's name is on the summer transfer shortlist of Serie A giants AC Milan.

The Rossoneri were among Europe's biggest spenders last year but in spite of that, are in danger of missing out on Champions League football next season.

As they look to strengthen once more, the Malaga native is a name being strongly considered by the Diavolo hierarchy.

Castillejo has been pinpointed in the event that another Spanish star, Suso, leaves the club during the summer and he has been linked with Napoli in recent days.
