Guillem Bauzà Mayol, who had appeared for Spain up to under-19 level, joined Exeter City from Northampton Town in 2011 having started his Football League career with Swansea City.  He made 46 league appearances during his two-year stay with the club before pursuing a medical sciences career.

Along with Andrés Iniesta and Fernando Torres, Guillem was a member of the Spanish team that won the under-16s European Championships in England in 2001. He also represented his country at under-17 and under-19 levels and appeared for Mallorca and Espanyol until signing for Roberto Martinez’s Swansea City in summer 2007 where he was best-remembered for scoring twice against Gillingham to secure the Swans’ promotion to the Championship. By the time he left the Liberty Stadium in May 2010 he had scored nine goals in 49 matches before, after trials with  Charlton Athletic and Sparta Rotterdam, signing for Hereford United in September 2010 and Northampton Town in March 2011.

Leaving Sixfields after just a few months, Guillem arrived at Exeter City ahead of the 2011/12 campaign and made a goalscoring debut against Yeovil Town in the League Cup on 9 August 2011 followed by netting on his first league appearance for the club against Brentford a week later. In a team that was to be relegated from League One, Guillem made a total of thirty league and cup appearances during his first term at St James' Park. 

Sustaining a series of injuries, he made fewer appearances in his second season and was released in May 2013 after making 51 first-team appearances of which 46 came in the league (including 30 from the bench). This proved to be the end of his Football League career as he returned to South Wales to play for Port Talbot Town and Merthyr Town and pick up the threads of his education which he had put to one side to concentrate on football. 

Gaining a first-class honours degree in medical genetics from Swansea University in July 2015, Guillem later completed a PhD before embarking on medical training with an initial interest in regenerative medicine. Eventually returning to Majorca, he subsequently moved into clinical research specialising in periodontics, implant dentistry and tissue regeneration.  

[Guillem is believed to have been the first Spanish-born player to appear for Exeter City since Antonio Cruz appeared for the ‘A’ team and reserves in 1958/59.]
