Tottenham have ended their long search for a permanent head coach by appointing Celtic boss Ange Postecoglou. Postecoglou, who won five major trophies in two seasons at Celtic, including this season’s domestic treble, faces a tough task to quickly turn Tottenham’s fortunes around. Here, the PA news agency takes a look at the 57-year-old’s in-tray. Resolve Harry Kane’s future The most pressing issue awaiting Postecoglou in his first job as a Premier League head coach is the future of Kane. The England captain has one year left on his contract and has been linked with a possible summer move to a host of Europe’s leading clubs, including Real Madrid, Manchester United and Bayern Munich. Postecoglou will want Kane to stay, but will also want assurances. The 29-year-old is either all in and stays, or opts for a new challenge and generates funds to help Tottenham rebuild their squad. Whatever Kane decides, Postecoglou will need a speedy decision. Unite the dressing room None of Tottenham’s near 30-man first-team squad are out of contract this summer, but plenty of departures can be expected. Postecoglou’s predecessor Antonio Conte publicly criticised his players’ team ethic and anyone lacking in that regard will have no place in the former Australia head coach’s squad. He must quickly work out who he can trust to fully commit to his principles and methods and try and move on those he does not. Unity and spirit were the bedrock for Celtic’s success under Postecoglou and he will want to lay the same foundations at Tottenham. Win over doubters Postecoglou was not top choice for the majority of Tottenham’s supporters and there will be plenty of scepticism among those who had called for the return of Mauricio Pochettino, while the likes of Arne Slot, Roberto De Zerbi and Luis Enrique were also reported to be on the club’s list of targets. Postecoglou must win over the doubters and reconnect the players with a disgruntled fanbase. He did just that at Celtic where he first took charge in a toxic environment, but can his blueprint for success in the Scottish Premiership transfer to the English top flight? Director of football key Tottenham have been without a director of football since the resignation of Fabio Paratici in April and the club will now prioritise that key appointment in readiness for a busy summer ahead. Feyenoord’s general manager Dennis te Kloese has turned down the role and, while filling the vacancy falls under chairman Daniel Levy’s remit, Postecoglou could well be involved in the process and will definitely want to strike an instant rapport with whoever takes on the job. The Australian has a clear philosophy for possession-based, high-energy football and the project will only work if the two parties are aligned. Top-four challenge European football has eluded Spurs for the first time since 2009-10 and they can ill-afford to miss out for a second successive season in their bid to retain their status as a ‘Big Six’ club. Postecoglou must overhaul the playing squad, galvanise a dispirited dressing room and bed in his backroom staff – what role, if any, for fans’ favourite Ryan Mason? – all in time to launch a Champions League challenge with the same brand of football that has thrilled Celtic fans for the past two years.
