The Scottish Premiership is home to one of the fiercest derbies in world football, with Celtic and Rangers battling it out to be top dog every season.

Both clubs have superior resources compared to the rest of the division, meaning they are able to spend more money on new signings.

Below, FootballTransfers runs through the 10 most expensive Scottish Premiership transfers of all time.

10. Michael Ball – €9.8m (Everton to Rangers, 2001)

Five months after his one and only England cap, Michael Ball left Everton to join Rangers for €9.8m amid the Toffees’ financial woes.

However, injury problems and the prospect of his transfer fee rising due to an appearance-based clause ensured Ball only played 70 games during a four-year spell in Glasgow. He joined PSV Eindhoven in 2005.

9. Adam Idah – €9.9m (Norwich to Celtic, 2024)

Adam Idah only mustered 17 goals in 117 first-team games for Norwich City, but Celtic opted to sign him on a permanent deal after a successful loan spell in 2023-24.

The Irishman averaged a goal every 65 minutes in the Scottish Premiership during his half-season loan spell and Celtic made the decision to purchase him for €9.9m in August 2024.

However, he subsequently failed to keep up his performance levels and increasingly found himself relegated to the bench. He was sold to Swansea for €6.9m in the summer of 2025.

8. Jota – €10m (Stade Rennais to Celtic, 2025)

Portuguese forward Jota features twice on this list, having been signed by Celtic permanently in 2022 and then again in January 2025. His second move to Parkhead was the cheaper one, as he had struggled after leaving the club.

Jota had impressed during his first spell at Celtic, which earned him a €29.1m move to Saudi giants Al-Ittihad in the summer of 2023. However, he immediately fell out with coach Nuno Espirito Santo and was sidelined after being de-registered from the Jeddah side’s Pro League squad.

He returned to the roster in January 2024 after Nuno’s sacking, but it wasn’t to last. He moved to Stade Rennais in the summer and, just six months later, was re-signed by Celtic for €10m.

7. Kim Min-su – €10m (Girona to Rangers, 2026)

Like many South Korean teenagers, Kim Min-su started his professional career in Spain, eventually ending up at Girona. He would only go on to make eight appearances for the Catalans, but he became a highly sought-after commodity following a successful loan spell at FC Andorra.

The versatile attacker scored eight goals and produced four assists in the second tier of Spanish football in 2025-26, which prompted Rangers to shell out €10m to sign him in summer 2026.

6. Odsonne Edouard – €10.3m (PSG to Celtic, 2018)

Odsonne Edouard became Celtic’s all-time record signing when he joined the club in 2018, with PSG earning €10.3m through the sale.

Edouard was adored by Celtic fans during his time in Scotland, but he left to join Crystal Palace in 2021. In total, the Frenchman scored 87 goals in 179 Celtic appearances.

5. Kevin Kelsy – €10.8m (Portland Timbers to Rangers, 2026)

Venezuelan forward Kevin Kelsy was already something of a journeyman in his early 20s, but he found a home with the Portland Timbers in MLS after joining in 2025. He got his big break the following year when he netted 10 goals in 23 appearances.

The Timbers did not want to lose the striker and rebuffed several approaches, but when Rangers bid €10.8m, it was deemed too good an offer to turn down.

4. Kasper Hogh – €12.9m (Bodo/Glimt to Celtic, 2026)

Celtic were desperate to sign Kasper Hogh in January 2026, but the Danish striker was in no rush to leave Bodo/Glimt, where he was enjoying a fairytale run in the Champions League.

After scoring against the likes of Man City, Atletico Madrid and Inter, Hogh felt that it was time to move on from the Norwegian side in the summer. Celtic’s persistence paid off as they managed to finalise a €12.9m deal for the attacker.

3. Arne Engels – €15.6m (Augsburg to Celtic, 2024)

Arne Engels joined Celtic in 2024 for an initial €11m following the sale of Matt O’Riley to Brighton & Hove Albion.

Engels arrived with much acclaim from Augsburg, having shone in the Bundesliga, and he scored once and provided one assist on his Champions League debut for the Scottish giants.

He became a reliable midfielder for the Hoops and attracted Premier League interest, which saw Nottingham Forest make a €30m bid for him in January 2026.

He was ultimately sold to relegated West Ham for €25.8m the following summer, which increased Celtic’s fee to Augsburg to €15.6m due to a sell-on clause.

2. Jota – €16.2m (Benfica to Celtic, 2022)

The aforementioned Jota initially joined Celtic on a permanent deal for around €7.8m in 2022, but the Bhoys were required to pay Benfica a total of €16.2m due to a 30% sell-on clause in the deal.

After 83 appearances and 28 goals for the club, Jota moved to Saudi Arabia for €29.1m, which ensured Celtic were forced to pay an additional fee to Benfica.

1. Tore Andre Flo – €18m (Chelsea to Rangers, 2000)

Tore Andre Flo is the most expensive signing in Scottish top-flight history. He joined Rangers from Chelsea for €18m in 2000, having netted 50 goals in 163 games for the Blues.

Flo spent just two years at Rangers, scoring 38 times, before returning to England with Sunderland in 2002. His time at Ibrox is widely considered to be a huge disappointment.
