Christian Pulisic has joined AC Milan from Chelsea. 

Milan beat off competition from Juventus, Lyon and Galatasaray to sign Pulisic on a $25.9 million transfer.

Pulisic becomes the third American to play for Milan after defender Oguchi Onyewu and Sergiño Dest.

"I'm very happy to be here. I'm excited. I'm excited to start with this historic club," Pulisic told reporters waiting for him at Milan's Malpensa airport on Wednesday before undergoing his medical. "It's legendary and I'm really excited to come here and try to win some titles here."
