Roberto Martinez, Paulo Sousa, Brendan Rodgers, Michael Laudrup, and Garry Monk – all managers who put their own stamp on things at Swansea City.
Martinez is widely seen as the instigator of the flowing, passing football now synonymous with the Swans. Sousa favoured a more direct, and in the eyes of some cynics, dour approach. Rodgers would obsess with possession and passing the opposition to death – while Laudrup looked to instil real threat from the flanks, and a cutting edge up front.
Monk meanwhile, has proved he is not afraid to adapt tactics, and has mixed an attacking style with the tendency to sit deep and counter attack away from home.
However, all five of the aforementioned figures have shared one tactical philosophy at the Liberty – that of playing a loan striker with support from the flanks and midfield.
Indeed, a Swansea City team playing a 4-4-2 formation has been a rare sighting since Kenny Jackett left the club during the 2006/2007 campaign – with such tactics confined to cup games or when chasing a late equaliser.
The signing of Eder this week was another signal of the growing intent at the club, with Huw Jenkins parting with £5 million for his services.
And there is no question that Swansea were in need of another forward; with little in the way of back up should anything happen to Bafetimbi Gomis.
The question is, has Eder been signed to cover the Frenchman, or play alongside him?
The former would mean an expensive substitute, the latter a change of formation.
And sure enough, the much publicised situation with Gomis in January, would surely have taught both Monk and Jenkins the perils of signing a big name, only for him not to be handed regular football. The irony of Wilfried Bony leaving the club was that had he not, then the now popular Gomis almost certainly would have.
As it happened, one of the 29-year-olds major gripes was his claim to have been signed on the promise of playing with Bony, as opposed to the role of his deputy.
And yet it would be surprise if Monk shifted from the formula that served him so successfully last season. Eder arrives with a moderately impressive scoring record from his time in Portugal, with 49 goals in 197 senior games, and a tally of one strike in 18 international appearances suggests he is yet to excel a Portugal shirt.
Few Swansea fans will ever doubt Jenkins and the shrewd manner with which he conducts his transfer business, but the 27-year-old Eder will still arrive in South Wales with much to prove.
Whether he will be seeking to prove himself in the Swansea City Premier League XI, or from the replacements bench and in League Cup ties, remains to be seen.
