Let’s start with those three clubs definitely needing a new manager – Chelsea, Crystal Palace and Manchester United.
Michael Carrick has done his chances of securing the United job on a full-time basis no harm at all while working on an interim basis since Ruben Amorim’s dismissal.
And their expected Champions League qualification will only serve to strengthen his claims to become the club’s next permanent boss.
Players are responding to the former United and England midfielder’s methods and have recorded some impressive results during his reign.
The club want their next manager to be a good coach but also someone with character and charisma to cope with the scrutiny that comes with the job.
As impressive as Carrick has been, he does not have the sort of experience of managing a club the size of United some inside the club believe to be a necessary component of their next boss.
If the appointment of a proven, big-name manager becomes achievable, United could yet pivot but, as things stand, Carrick is a strong candidate.
Elsewhere, Rosenior’s sacking means Chelsea’s US owners need to appoint a fifth full-time manager since their arrival in 2022.
Chelsea insist they are not in active discussions with any candidates at this moment, though it is understood internal discussions over their priority targets are under way.
Landing their preferred candidates may be easier said than done, though, with a number of industry sources indicating the difficulties predecessors have run into over recruitment in recent years may mean top managers are reluctant.
Iraola is expected to be high on the club’s final shortlist of candidates given his excellent work at Bournemouth while Fulham boss Silva is another who is likely to be discussed if he decides not to renew his contract.
Edin Terzic – a contender for the Athletic Bilbao vacancy, Alonso and Cesc Fabregas may also emerge as candidates, while the club are mindful of Howe’s potential availability this summer.
Oliver Glasner has already confirmed he will be leaving Crystal Palace this summer, and the club are well down the line of completing checks on potential replacements.
BBC Sport revealed in January that Palace had an interest in Iraola, and that remains.
The Spaniard is viewed internally as one of their lead targets. He is aware of Palace’s interest, and the Eagles are still of the belief they have a good chance of appointing the 43-year-old.
Should he agree to the move, Palace would be prepared to give Iraola heavy influence on the club’s recruitment strategy.
Sources have indicated that Coventry boss Frank Lampard, former Brentford and Spurs manager Thomas Frank, Ipswich counterpart Kieran McKenna and Sean Dyche – most recently of Nottingham Forest – are also among the contenders.
It is understood Dyche would have been a serious contender to replace Glasner had the Austrian been dismissed earlier this year.
