Celtic confirm Martin O'Neill as manager: Contract details, assistants and what Dermot Desmond said

It emerged last week that O’Neill has agreed a one-year contract at Celtic Park after guiding the club to the Premiership title and Scottish Cup last season.

The 74-year-old Northern Irishman returned to Celtic not once but twice to answer an SOS call from principal shareholder Dermot Desmond following the resignation of Brendan Rodgers and then the ill-fated 33-day tenure of Wilfried Nancy.

It has not yet been confirmed who O’Neill’s assistants will be, with reports on Thursday claiming Shaun Maloney and Mark Fotheringham have been offered reduced terms to stay at the club.

In a club statement, Celtic wrote: “Celtic Football Club is delighted to announce the appointment of Martin O’Neill as Football Manager on a one-year contract with a one-year option.

“In his connection with Celtic, Martin has already brought nine major honours to the club, including Celtic’s fifth consecutive league title as part of the most memorable league and Scottish Cup double just last month.

“Among his many achievements, Martin was the first manager to deliver a domestic Treble for Celtic in 32 years, when he did so in his first season in charge back in 2001, while he also took Celtic to a European final in Seville in 2003.

“Last season, he drove the club to its 56th Premiership title, by winning the last seven league matches and rounding off one of the most amazing climaxes in Scottish football history by securing his fourth and Celtic’s 43rd Scottish Cup victory.”

What Desmond said on O’Neill return

Celtic’s principal shareholder Dermot Desmond said: “Time and time again Martin has shown his qualities and what he can bring to Celtic.

“We know he is a winner, we know what the club means to him and he continues to be the outstanding candidate to give us the best opportunity to realise our objectives.

“He knows the demands at Celtic and I know how determined he is again to bring success to the club and to our supporters.

“The club will support Martin fully again across the close season to make sure we are well prepared to achieve domestic success and compete on the European stage.”

Michael Nicholson, Celtic’s chief executive, said: “We are really pleased to keep Martin as manager. His knowledge and experience proved vital to us last season and we know his leadership will be hugely important to us going forward.

“He is someone who continues to deliver, who knows how to win and a manager we have absolute confidence in to once again drive the team through the next period.

“We have important challenges ahead and the immediate priority of everyone at the club is to ensure we are ready to tackle these with confidence and deliver success again for our supporters.”

And interim chairman Brian Wilson added: “I warmly welcome Martin's re-appointment and look forward to more of the same leadership, inspiration and success he has delivered for the club.

“The achievements which he and the team secured in the season just gone have created a great platform for the one that lies ahead.

“This is the start of a busy summer and we will ensure that we are in the best possible position to compete, with Martin back at the helm.”
