The England youth international joined Wanderers in September 2014 after a compensation package was agreed with his former club, Crewe Alexandra.
The forward had spent his entire career to date with the Railwaymen, having come through the club’s famous youth academy system.
Son of former Crewe and Norwich City striker Paul, Clayton made his debut for the Alex in April 2011 against Morecambe, before scoring on his first start for the club against Macclesfield Town in October 2011.
A member of the Crewe side that won promotion to League One via the play-offs in 2012, Clayton scored in the second leg of the club’s semi-final victory Southend United, before coming on as a substitute in the final against Cheltenham Town.
Clayton played at Wembley again the following year as Crewe reached the Johnstone’s Paint Trophy Final, with the forward scoring his side’s second goal as they beat Southend United 2-0 to lift the trophy.
Wanderers fought off a number of clubs to land the highly-rated forward’s signature, with Clayton having even played for Sunderland during pre-season in the Mackems’ 5-1 friendly win over Darlington.
Handed his first team debut against Bournemouth in October 2014, Clayton established himself as a regular under Neil Lennon after scoring his first goal for Bolton in front of the Sky cameras in a televised Friday night derby against local rivals Wigan Athletic.
However, his season was ended prematurely just a month later after the forward ruptured his interior cruciate ligament against Ipswich Town.
Returning the following September, the versatile forward made eight appearances during the 2015/16 season before a hamstring injury once again ended his season prematurely.
Having featured for Phil Parkinson's side in pre-season, Clayton is currently side-lined with a knee injury as he looks to slowly nurse his way back to full fitness.
