Postecoglou led Tottenham to their first UEFA trophy in 45 years by winning the Europa League title this season. This achievement also secured a spot in next season's Champions League for the club.
However, Tottenham's poor performance in the Premier League, which saw them finish 17th, has led to Postecoglou's dismissal despite the team's injury crisis throughout the season.
According to reports, if Tottenham makes an offer to Frank, Brentford will insist on a £10m fee to release him from his contract. Frank still has two years left on his current deal with the Bees.
Frank's departure could be a significant loss for Brentford, but the club is likely to prioritize a substantial compensation fee to offset the loss of their valued manager.
Brentford will likely negotiate with Tottenham to secure a fair compensation for Frank's release from his contract.
