Kyei joined the academy at Barnet aged nine and stayed with the club through to senior level.

He made his Football League debut when he started against Crawley Town on the final day of the 2015-16 season.

Kyei joined Concord Rangers on loan on 5 November 2018.

He then joined Hampton & Richmond Borough on loan on 11 January 2019.

Kyei went out on loan for a third time when he joined Potters Bar Town on loan deadline day on 28 March 2019.

He was released by the Bees at the end of the 2018–19 season before joining Maidstone United on 1 July 2019.

After 17 appearances and 4 goals, Kyei left Maidstone United by mutual consent in December 2019 when he signed for Chelmsford City.

Manager Lee O'Leary and Technical Director Adam Waller have been following Nana’s progression after impressing everyone during last seasons loan spell.

So it comes with no surprise that It didn’t take much discussions or negotiations in seeing the pacey winger return, however, this time in a permanent deal.
