[Getty Images]Chelsea remain one of European football's biggest draws - and despite this season's difficulties, high-profile managers will inevitably be attracted to the vacancy.Marco Silva, the Fulham manager, is set to be a candidate for the position this summer.The Portuguese's deal expires at the end of the season, meaning Chelsea would not have to pay Fulham or negotiate to release him from a contract.The fact he is represented by agent Jorge Mendes, who has a close relationship with Chelsea's ownership, would also ease any move for Silva.That said, sources have told BBC Sport that working within the club's current model is causing hesitation from coaches who would normally be considered for the role.For instance, outgoing Bournemouth head coach Andoni Iraola is of interest to Chelsea's leadership group - but those close to the Spaniard have indicated he will prioritise stability at his next post - not a trait associated with Chelsea at present.In addition, the 43-year-old is understood to want to return with his family to Spain after deciding against signing a new Bournemouth deal.Edin Terzic, who led Borussia Dortmund to a Champions League final in 2024, is under consideration, while former Chelsea midfielder Cesc Fabregas is earning rave reviews at Serie A club Como.Xabi Alonso is out of work, having left Real Madrid earlier this season.The question is whether any of those names, if approached, would express reservations about working within the Chelsea recruitment model - of bringing in younger players who can develop. And then there is the club's recent history of dispensing with managers.That said, Chelsea are understood to be contemplating a change in approach this summer with a view to targeting more experienced signings to complement their young team.Landing more established talent this summer may be easier said than done.The club recently posted a £262.4m loss for the 2024-25 season - the highest pre-tax loss in Premier League history.That, coupled with the prospect of missing out on Champions League football, is expected to restrict spending in this summer's transfer window.The club remain confident they can attract the right coach, though they are not in active talks with any candidates and do not expect to appoint a full-time replacement until the end of the season.They are looking for someone who can win matches and, ultimately, deliver trophies.Who should Chelsea's next permanent manager be?
