CELTIC have announced that Jonny Hayes and Jozo Simunovic will both be leaving the Parkhead club this summer.

Republic of Ireland internationalist Hayes took to Instagram last night to reveal that he would be departing when his current contract expires at the end of this month.

But the Scottish champions have confirmed that they won't be taking up the option to extend Simunovic's contract for another year.

The former Dinamo Zagreb centre half has been troubled by injuries since joining the Glasgow club in 2015.

The defender made 125 appearances and scored five goals - including an emotional and poignant winner against Kilmarnock in April last year following the sad passing of club legend Billy McNeill.

Celtic manager Neil Lennon said: "I would like to sincerely thank both Jozo and Jonny, brilliant lads who have given their all to Celtic over a number of years.

"Jozo has been part of our great club for some time and has given us some wonderful times, playing a really important part in our success. Jonny, too, has been an important player for the club in recent years.

"Above all, both are great men and everyone at Celtic wishes Jozo and Jonny and their families all the very best for the future. We are sure they will continue to be successful in everything they do.

"Both players leave Celtic as Nine-In-A-Row champions, something they have earned, an achievement they richly deserve and something I know they will cherish dearly."
