Celtic are on the lookout for a new head coach after Ange Postecoglou officially left the Scottish giants to join the Premier League on Tuesday.
The 57-year-old has put pen to paper on a deal with Tottenham Hotspur in England and this now pushes Peter and Mark Lawwell and Dermot Desmond into the market to bring a manager in to replace the Australian.
A number of bosses have already been linked with the vacancy and one man who is reportedly in the running for the job is ex-Leeds United coach Jesse Marsch.
The 49-year-old, who won two Austrian Bundesliga titles in two seasons with RB Salzburg earlier in his career, could revive a current Celtic outcast back to his former glory if the Hoops decide to appoint him heading into next term.
How did David Turnbull perform this season?
Parkhead attacking midfielder David Turnbull endured a difficult 2022/23 campaign as the Scotsman only started six games in the Scottish Premiership and zero times in the Champions League.
He made 27 appearances as a substitute in the two competitions combined but his lack of starts limited the impact that he was able to make in the final third. The gem ended the season with four goals and six assists in the league and in Europe combined, which shows that the ace was unable to make regular contributions in attack.
Turnbull is a number ten by trade and did not fit in with Postecoglou's 4-3-3 system, which required him to play as an eight or out wide, and thus could be revived by Marsch's preferred 4-2-3-1 set-up that would allow him to play in the hole behind a centre-forward.
The American's formation would provide the 23-year-old with two holding midfielders behind him to offer defensive protection and allow the ace to push forward to link up with the two wingers and striker to create and score goals at the top end of the pitch.
Celtic's Scotland international predominantly played as a number ten for Neil Lennon in the 2020/21 campaign, before Postecoglou's arrival, and enjoyed a terrific year in the Premiership, which the Australian later described as "outstanding".
The £16k-per-week magician averaged a Sofascore rating of 7.47 and contributed with nine goals and six assists in 30 starts. He also created 12 'big chances' for his teammates and made 2.9 key passes per match, which is more than any Celtic player averaged in the league this year.
Therefore, Marsch, whose style was described as "aggressive" by journalist Josh Bunting, could revive the Hoops wizard by making him the attacking midfielder in his 4-2-3-1 system, which could allow the ace to thrive and get back to regularly scoring and creating goals in the Premiership.
