The transfer window is now open and Wanderers already have a healthy portion of their squad tied down for at least the next couple of seasons.

The Whites received a major boost last month as captain Ricardo Santos put pen to paper over a new three-year contract at the UniBol.

Earlier this year, Ian Evatt said he expected to be tested in the transfer market but warned that clubs interested in his players are going to need "deep pockets".

Here are the biggest transfer fees Wanderers have received over the years from the likes of Chelsea and Aston Villa

Nicolas Anelka

The Bolton News:

Sam Allardyce signed Anelka from Turkish side Fenerbahce in 2006 and the Frenchman had a big impact at the UniBol, scoring 23 goals in 61 games.

He made the move to Chelsea in January 2008 for a £15million fee, which remains the highest amount the Whites have ever received for a player.

Anelka went on to have a successful career at Stamford Bridge and also had stints at Juventus and West Brom among others before hanging up his boots.

Gary Cahill

The Bolton News:

Cahill joined Wanderers from Aston Villa in January 2008 and went on to make 147 appearances for the club.

He also made the move to Chelsea four years later for a fee in the region of £7million and went on to win two Premier League titles as well as having success in Europe.

The former England international has since had spells with Crystal Palace and more recently Bournemouth, and is currently a free agent.

Gary Madine

The Bolton News:

Madine arrived at the UniBol in the summer of 2015 following spells with Sheffield Wednesday and Blackpool among others.

The forward scored 26 goals in 107 appearances for the Whites before he was sold to Cardiff for a fee in the region of £6million as the club tried to balance the books.

However, Madine’s time at the Welsh club didn’t go to plan and he is now back at Blackpool, having scored nine goals for the Seasiders last season.

Eidur Gudjohnsen

The Bolton News:

Gudjohnsen joined Wanderers in 1998 and spent two years in the North West before heading to Chelsea for a reported £5million fee.

The forward went on to have spells at Barcelona and Tottenham among others before returning to the UniBol in 2014 on a short-term deal.

He announced his retirement in 2017 and most recently had a spell as assistant manager for the Iceland national side.

Alan Thompson

The Bolton News:

Thompson made the move to Bolton in 1993 and went on to make 198 appearances during a memorable five-year spell at the club.

The midfielder left to join Aston Villa for a reported £4.8million fee and also had spells with Celtic, Leeds and Hartlepool.

After hanging up his boots, Thompson held coaching roles at Newcastle, Birmingham and Bury among others and has also worked as a pundit.

Jason McAteer

The Bolton News:

McAteer joined Wanderers in 1992 after impressing in non-league and went on to make 145 appearances during a three-and-a-half-year spell at Burnden Park.

The versatile midfielder left the Whites to complete a dream move to boyhood club Liverpool for a fee in the region of £4.5million.

McAteer later had stints at Blackburn, Sunderland and Tranmere before announcing his retirement in 2007 and has also worked as a pundit.

Sasa Curcic

The Bolton News:

Wanderers signed Curcic from Partizan Belgrade back in 1995 and the Serbian dazzled supporters with his silky skills.

But after just one season in the North West, the midfielder made the move to Aston Villa for a reported £4million fee.

Curcic’s life after calling time on his career has varied from running football academies in London to appearing on Serbian reality television.
