Here we take a look at their best players who arrived on a free transfer and went on to make telling contributions. We feature those signed since 2010.
5. Gaetan Bong
Completes the back four of our free transfer XI. The left back arrived on a free from Wigan in 2015-16. A dependable player for Albion and departed earlier this year for Forest.
6. Inigo Calderon
What a player for Albion. Arrived from Alaves in 2010 and went on to make 198 appearances and a key man in helping Brighton rise up the ranks to the Premier League.
7. Steve Sidwell
Arrived from Stoke in 2016-17 and retired from football in 2018. A decent on the ball and very in the tackle. The 37-year-old is now a pundit on BBC.
8. Beram Kayal
Arrived from Celtic in 2014-15.118 appearances for the Albion and a fine technician in the midfield. Had his loan spell at Charlton cut short with injury this season and is now back at Albion, where his contract expires in June.
