Dundalk sign former Derry City and NI U21 winger Michael Duffy from Celtic
Dundalk have signed former Derry City winger Michael Duffy from Celtic.
Duffy, 22, has been on loan at Scottish Premiership side Dundee this season after a previous loan spell at Alloa during his two-year Celtic stint.
"I enjoyed my two years in Scotland. I played in some big games and made a good lot of friends," Duffy told the Dundalk FC website.
"It just didn't work out the way I wanted it to but I still enjoyed it. I'm now buzzing to join Dundalk."
Duffy - who played with Dundalk midfielder Patrick McEleney at Derry - was last year called up to the Northern Ireland senior squad by Michael O'Neill.
The winger has played for the Northern Ireland Under-21s.
