The former West Bromwich Albion captain arrived at Elland Road after weeks of transfer negotiations for a fee of ?500,000 that could rise to ?1m based on appearances and promotion bonuses.

The midfielder arrived in Leeds with over 450 games under his belt and represented the type of experience Kevin Blackwell was desperately trying to add to his squad.

He also brings real leadership qualities and during his time at the Hawthorns and previous clubs Preston and Darlington, an uncompromising, tough tackler.

Gregan began life as a defender with Darlington and helped guide them to the old Fourth Division championship before David Moyes signed him for Second Division Preston North End in a ?350,000 move in November 1996.

It was whilst at Preston that he was turned into a midfielder, and made captain. He was voted Preston North End Player of the Year in 1999/00 - the same year he helped the Lilleywhites win the Second Division championship.

He joined West Brom in August 2002 for ?1.5m and quickly became a crowd favourite there too, taking on the captaincy and guiding them back to the Premiership at the first time of asking last season.

But he fell out of favour with Baggies boss Gary Megson and that allowed Kevin Blackwell to make his move.

One of Sean's claims to fame is that he once scored from the half-way line, playing against Norwich in March 2001.
