Brighton have completed the signing of international defender Shane Duffy, it was announced on Friday.

The Championship club have confirmed on their official website that Duffy, 24, has joined from second-tier rivals Blackburn on a four-year contract for an undisclosed fee.

The Daily Record reported last month that Celtic were interested in signing the centre-back after his impressive performances with Northern Ireland at Euro 2016.

Duffy joined Blackburn two years ago from Everton and starred in 42 appearances for the Lancashire club last season in all competitions.

The defender has elected to help Brighton push for promotion from the Championship instead of joining the home of the Scottish champions.

Celtic managed to reach the Champions League group stages and were handed a difficult group on Thursday, drawing Barcelona, Manchester City and Borussia Monchengladbach.

Brendan Rodgers has several experienced defenders in his squad despite missing out on Duffy.

Eoghan O’Connell, Mikael Lustig, Dedryck Boyata and Kolo Toure are all senior options for Celtic at centre-back and should provide enough cover for this season.

In other Celtic transfer news, a medical is underway as the club are set to clinch a £2million deal for a midfielder.
