Ronald Koeman‘s managerial career has been marked by shrewd signings that transformed both Southampton and Everton. As he prepares to return to St Mary’s, Baji live revisits his most impactful acquisitions—players who defined his tactical vision and left lasting legacies at their respective clubs.
Koeman’s Goalkeeping Masterstroke: Fraser Forster
Fraser Forster’s £10m move from Celtic to Southampton in 2014 was a statement signing. Under Koeman, the towering goalkeeper became a Premier League stalwart, earning England call-ups and delivering clutch performances. His reflexes and command of the box were instrumental in Southampton’s rise under the Dutchman.

Defensive Pillars: Virgil van Dijk and Ashley Williams
Virgil van Dijk: The £13m Bargain
Southampton’s acquisition of Van Dijk from Celtic was a masterclass in scouting. The Dutch defender’s composure, aerial dominance, and ball-playing ability made him one of the league’s best. His partnership with José Fonte was the backbone of Koeman’s defensive structure.
Ashley Williams: Leadership at Everton
Koeman’s £12m signing of Williams from Swansea brought experience to Everton’s backline. Though the Toffees have struggled defensively at times, Williams’ leadership and tenacity remain invaluable.
Full-Back Brilliance: Cedric Soares and Ryan Bertrand
Cedric Soares: The Portuguese Dynamo
Replacing Nathaniel Clyne was no easy task, but Cedric’s £4.7m arrival from Sporting Lisbon proved astute. His Euro 2016 triumph with Portugal showcased his potential, and he remains a key figure at Southampton.
Ryan Bertrand: From Loanee to England Regular
Bertrand’s £10m permanent move after an initial loan solidified Southampton’s left flank. His attacking overlaps and defensive discipline earned him a place in England’s setup.
Midfield Maestros: Oriol Romeu and Idrissa Gueye
Oriol Romeu: The £5m Steel
Romeu flourished after Victor Wanyama’s departure, becoming a midfield destroyer under Koeman. His tackling and positional awareness made him indispensable.
Idrissa Gueye: Everton’s Engine
Gueye’s £7.1m signing from Aston Villa was a revelation. His relentless work rate and ball-winning ability transformed Everton’s midfield—his absence in the 5-0 Chelsea thrashing highlighted his importance.
Attacking Flair: Tadic, Mane, and Bolasie
Dusan Tadic: The Creative Spark
Tadic’s £10.9m signing replaced Adam Lallana seamlessly. His vision and creativity were central to Koeman’s attacking play, epitomized by his four assists in an 8-0 demolition of Sunderland.
Sadio Mane: From Obscurity to Stardom
Mane’s £10m move from Salzburg was a gamble that paid off. His blistering pace and 25 goals in two seasons earned him a Liverpool transfer—and a place in Premier League history with the fastest hat-trick (2:56).
Yannick Bolasie: Everton’s Wing Wizard
Bolasie’s £28m arrival from Crystal Palace added flair to Everton’s attack. Though his goal output was modest, his link-up play with Romelu Lukaku was electric.

The Clinical Finisher: Charlie Austin
Austin’s £4m signing was a bargain. His winner at Old Trafford against Manchester United was iconic, and his current form under Claude Puel (8 goals this season) proves his enduring quality.
Conclusion: Koeman’s £114.7m Legacy
Ronald Koeman’s eye for talent shaped Southampton’s rise and Everton’s rebuild. His best XI—featuring Forster, Van Dijk, Mane, and Gueye—showcases his ability to blend value and quality. As he returns to St Mary’s, Baji live reflects on a legacy built on smart recruitment and tactical acumen.
