Sources told ESPN that the Tottenham Hotspur manager will learn about his fate this week after the club began announcing a board change on Monday.

Sources told ESPN that Postecoglou's job is at risk — despite the 59-year-old who believes he is at high risk of losing his job — won the trophy last month despite winning the Spurs' 17-year wait trophy last month.

Postecoglou oversees the Spurs' worst Premier League season ever, including 22 defeats - the most of the season without team relegation - and is on vacation after admitting he's not sure he'll see the last two years of his contract.

Sources told ESPN that new CEO Vinai Venkatesham has now begun working at the club and he will play a role in determining the manager's fate as part of a series of changes to the club's structure.

Postecoglou said in an interview with the ABC on a family holiday in Greece on Monday that he didn't want the club to "enjoy this moment" because he "hopefully we think about the next step".

“Don’t be satisfied with that,” he told ABC’s Australian story. "We have the taste of it now. My players know something about it. The taste of the club. Well, let's make sure we're back here."

Possible replacements for postecoglou include Brentford boss Thomas Frank, Fulham's Marco Silva and Bournemouth manager Andoni Iraola, though the latter is expected to sign a new contract to stay on the South Coast.

The final decision is expected in the coming days of Europe, but earlier on Monday, Tottenham Hotspur announced that Coulen would resign as chairman Daniel Levy’s most trusted consultant.

Cullen, who joined the Spurs Council in 2006 and is a trustee of the Tottenham Hotspur Foundation, said in a statement: "It's a difficult decision. Clubs have been my life for the past three decades. I have had the honor of working with Daniel.

“It’s been a pretty good journey, starting with White Hart Lane, a short stop at Wembley and ending with our new home – amazing memories. At the end of the season, ending with the Europa League Trophy, it’s a dream come true.

"It's time for me to collect more time for myself and my family and I'm grateful for all their support over the years. I'm going to spend months making sure the exchange with my staff goes well. Thank you everyone. I hope everyone at the club is successful in the world."

Levi said: “Donna has made a huge contribution to the club for a long time. Her diverse responsibilities have grown a lot and it would be impossible to replace her role with one person.

“While many may have primarily linked her to marketing and communications, Donna’s influence goes far beyond these areas. In particular, her leadership and political acumen on the Planning Commission, played a role in the club and was able to build one of the best stadiums and training centers in the world.”

Venkatesham has been advertising the role of candidates working with him, while also having big questions about the position of Chief Football Officer Scott Munn and the possible changes to the medical and sports science team.
