Tim Sherwood is favourite to become West Brom head coach - but will not agree a deal until his backroom staff receive improved terms.
The former Tottenham manager is understood to be happy with the terms after being interviewed for the vacancy earlier this week.
But Sherwood wants better offers for coaches Chris Ramsey and Les Ferdinand.
Sherwood, 45, has told West Brom chairman Jeremy Peace he will not take the job without the duo onboard.
West Brom insist Sherwood is not the only one being closely considered for the job.
BBC Sport's Pat Murphy said: "I understand there's a substantial gap between West Brom's offer and what Ramsey and Ferdinand expect.
"Sherwood's perfectly happy with his terms and contract but he won't budge over what he believes is a derisory offer to Ramsey and Ferdinand."
West Brom had been expected to name the replacement for Pepe Mel before the weekend, having concluded the interview process by Tuesday of this week.
The Baggies finished 17th in the Premier League in 2013-14, and Mel left his role as head coach on 12 May.
The Spaniard was the club's second head coach of the season, Steve Clarke having departed in December after four successive defeats.
He took charge at White Hart Lane on an interim basis on 16 December and was given the job full-time a week later.
The former Spurs midfielder led the club to a sixth-place finish and Europa League qualification, but left despite a top-flight win percentage of 59% - the best of any Tottenham boss in the Premier League.
His record impressed West Brom, as did his work with young players while working as technical co-ordinator at Spurs.
Former Southampton boss Mauricio Pochettino replaced Sherwood as Tottenham manager.
