Chelsea fans have been jumping with delight after witnessing what Christian Pulisic has been doing in his attempts to be ready for when he joins up with Frank Lampard's squad.

The United States of America international has been busy with his national side this summer as he helped take them to the Gold Cup Final, although they had to settle as runners-up as they were beaten by Mexico in their own backyard.

Pulisic played a vital role for Gregg Berhalter's side throughout the tournament and saw his performances rewarded as he was named the Young Player of the competition, as the 20-year-old managed to net three goals and provide three assists in his six appearances (Transfermarkt).

The £58million January signing (BBC) is expected to join up with Chelsea and Lampard following the conclusion of their tour of Ireland (Sky Sports) as fans will want to see him in action for the first time.

And, it would seem many of the supporters are already keen to see what he will bring to Stamford Bridge after witnessing the video his father posted on Twitter.

Despite being just one week removed from their Gold Cup defeat, Pulisic is shown going through the motions and working hard to ensure he is ready for the club's upcoming tour to Japan.

Fans flocked to the social media site to leave their responses, with many pleased to see the dedication and the professionalism he was showing, with one believing he would turn into a Chelsea legend in the future.

Here are just some of the Chelsea faithful's reactions...
