COMMENT: Unai Emery's men have battled all the way to the Europa League final against Benfica and their Croatian midfield dynamo remains integral to their chances
Alongside valuable cantera products Jose Antonio Reyes, Sergio Ramos and Jesus Navas, the club signed Dani Alves, Julio Baptista, Adriano, Seydou Keita, Geoffrey Kondogbia, Gary Medel and others on the cheap before offloading for far greater sums.
Now, Sevilla could be about to dwarf all of those deals as speculation engulfs their current star man: Ivan Rakitic.
After notching 13 goals and as many assists in all competitions, Rakitic is having easily his best-ever campaign. He has played a huge role in helping the club put two utterly dismal years behind them.
The 26-year-old has been the team's main driving force and a set-piece sensation. Despite being such a decisive factor in the final third, it would be short-sighted to look no further than his creative ingenuity.
After appearing lightweight and even shy in his earlier days in Seville, the modern Rakitic is notably combative. With his upright running style and all-round powerful figure, he is now more physically imposing than the skinny 22-year-old initially signed from Schalke in January 2011.
With his contract coming close to an end, the Germans opted to sell Rakitic to avoid missing out on a transfer fee. Although Atletico Madrid and Juventus were reportedly interested, Sevilla pounced and signed him for just €2.5 million (£2m).
Despite catching the eye immediately after his move, Rakitic has not always looked destined for the top. Like in his final few months at Schalke, the Croatian was just another inconsistent midfielder in his first full season in Spain.
New coach Marcelino Garcia Toral implemented a 4-4-2 system in order to accommodate an attacking partnership of Frederic Kanoute and Alvaro Negredo, meaning that Rakitic played in an exceptionally deep role.
Michel replaced Marcelino in February 2012 but Rakitic's position hardly changed. A 4-2-3-1 formation might have been introduced but Kanoute filled the space behind Negredo, while the Croatian slotted into defensive midfield once again.
The 2011-12 Primera Division season proved to be goalless for Rakitic and he started 17 matches on the bench. It is difficult to imagine now, given his hero status in the red-and-white half of the city, but some fans had started to get on his back.
Arguably the most important day in the midfielder's Sevilla career to date was when fan favourite Kanoute left for Beijing Guoan. The Malian's departure left a gaping void in the attacking midfield position and Michel opted to move Rakitic into that advanced role; the former Real Madrid star's only lasting impression from an ill-fated spell as coach. The Croatian has not looked back since.
Last season saw the rugged yet elegant Rakitic blossom, netting eight league goals and 10 assists. It was clear that a mass exodus was going to befall the club during the summer of 2013 but Sevilla were adamant that their midfield gem was going nowhere and they subsequently named him captain.
With virtually an entirely new squad built around Rakitic, Sevilla finally appear to getting close to the heights supporters expect as they close in on a fifth-place league finish and could yet win the Europa League.
His spectacular, headline-grabbing performance in this season's 2-1 home win against Real Madrid exhibited just how much he has improved in big games but, just as contract issues played into their hands when signing the Basel youth product, they are also making a summer exit look likely.
Rakitic's current deal expires in June 2015 and although his agent and brother, Dejan, is in talks regarding a renewal, Sevilla are understandably losing patience, with the process becoming exceedingly drawn-out.
The player's representative reportedly suggested that any new contract would have to include a buyout clause well below €20m (£16.3m), something Sevilla dismissed immediately with that figure currently standing at €40m (£32.6m).
Of course, it remains to be seen what happens with this apparent roadblock but the World Cup is likely to at least help provide an answer.
The Swiss-born Croatia international, who has 60 caps to his name, is expected to be one of the players who really emerges internationally in Brazil this summer but he will hope not to be shunted out to the right wing as he has been in the past.
In theory – and depending on the formation – he should form a central trio with Luka Modric and either Mateo Kovacic or Ognjen Vukojevic but Rakitic's form at club level means that coach Niko Kovac must deploy him just behind Mario Mandzukic.
Although Sevilla would not want to see their leader make a move, the better that he performs in Brazil, the more likely that a team will meet his buyout clause, and Rakitic's own father claimed during the winter break that his son will break Croatia's record transfer: Modric to Real Madrid for €30m (£24.4m).
There was no indication as to who would make the offer or when it will happen but Rakitic has arguably had an even bigger impact on Sevilla than Modric had on Tottenham and a host of clubs are on his trail. Either way, Monchi will probably be handed a substantial cheque once again rather soon.
