Mason Burstow full of pride after first senior training session at Chelsea | OneFootball

Mason Burstow was full of pride after completing his first training session with the senior squad at Chelsea.

The Blues bagged Burstow from Charlton on January's transfer deadline day.

But he remained at Charlton until the season concluded.

And now, the 18-year-old has joined his new team-mates on the training ground for the first time.

He said on a pic of him in the Blues kit flanked by his teammates: "First session with the first team."

Burstow made his U23 debut for Chelsea in the final game of last season.
