The Bantams have clinched their sixth signing of the summer by securing the services of Shane Duff.

The imposing central defender left Cheltenham Town in the summer after over ten years service with the Robins and has now joined the Bantams on a one year deal.

The football club also have the option to extend the deal by a further year should they wish to do so.

Duff had been offered a new contract to stay at Cheltenham, but he has decided to end his association with the Gloucestershire based club to become a Bantam.

After signing his contract, Duff quickly joined up with his new team-mates as they began their second day of pre-season training.

Capped at Under 21 level with Northern Ireland, the 6' 1'' defender will now take his place in Peter Taylor's squad with the aim of securing a place in his starting eleven for the visit to Shrewsbury Town in the season opener.

Duff, 28, was a huge fans favourite at the Abbey Business Stadium during his long spell at Cheltenham, mainly thanks to his hugely impressive and consistent performances at the heart of the Robins defence.

Apart from a brief loan spell at non-league Evensham United in 2001, Duff has spent all his career with Cheltenham before his move to City.

During his time at Cheltenham Town, he was named their Player of the Year in 2004/05 and played an integral part in not only helping them to promotion into League 1 in 2006, but helping to retain their third tier status the following season.

A damaged achilles tendon suffered during the Bantams amazing 5-4 win at the Abbey Business Stadium back in August 2009 robbed Duff of the majority of last season.

After six months on the sidelines however, he returned to full fitness to help the Robins retain their place in League 2 at the back end of the season.

Football clearly runs in the Duff family, as his brother Michael is also a professional footballer at Burnley.

The former Cheltenham captain is also a talented Cricketer and once played at Lords in 2002 at a National Village finals day.
