In the 6 years that Llewellyn spent in the first team it was rumoured that on more than one occasion an unknown Premiership club had had an offer of 3 million pound plus rejected by Norwich, who were keen to keep hold of the player dubbed, 'The New Giggs.'

Llewellyn signed for Wrexham and a strong 2003–04 season saw him recalled to the Welsh squad in May 2004 and come on a sub to win his third cap against Norway.

After coming from 1–0 down, Llewellyn scored the goal which handed the Red Dragons a 2–1 lead before they eventually won 3–1 and preserved their Football League Two status.

[6] Llewellyn was released by Grimsby at the end of the 2008–09 season and joined Welsh Premier League side Neath Athletic.

[6] After scoring five times in the opening five games of the season, Neath manager Andrew Dyer praised Llewellyn's performances and described him as "the best striker in the league".

[13] On 12 August 2021 Swansea City Ladies appointed Chris Llewellyn as head coach,[14] but he left after less than a month in charge.

Llewellyn scored his first international goal for Wales against Liechtenstein in November 2006 alongside his ex Norwich City strike partner Craig Bellamy.
