Born in Portsmouth on 23 June 1995, John joined Chelsea as an Under-14 and is a hard-working box-to-box midfielder who is technically strong and capable of scoring the odd goal, as demonstrated by his four strikes in 28 youth team games in 2011/12, his first full-time season. He was rewarded with a pro contract in the summer.
John impressed as an ever-present in the triumphant Youth Cup campaign of 2011/12, netting in the opening round, and was given his first taste of reserve team football as a substitute.
During the current campaign the young midfielder has featured for both the Under-21s and Under-18s, playing in both the NextGen Series and the FA Youth Cup.
Swift came off the bench to inspire a semi-final win over Arsenal in the NextGen Series, supplying the cross from which Lewis Baker scored the winner in a 4-3 win.
He has been coming into a good run of form of late, and scored for the Blues in our semi-final second leg Youth Cup win against Liverpool at Stamford Bridge, cancelling out the visitors' opener with an excellent finish on the break after starting the move in his own half.
Earlier this season Swift made his debut for England Under-19s.
