United have beaten off competition from both West Bromwich Albion and Brighton to sign the 17-year-old and he will be added to Elliott Dickman’s Under-23 squad next season. Murphy has already captained the Republic of Ireland at youth level and is regarded as one of the brightest stars in his country.
“He is a very promising young player who has attracted a lot of attention from clubs. It is a real coup for our Academy and is a testament to the direction the club is going in under our owners.
“I would like to thank everyone involved with Galway United for their assistance. “The club has been a pleasure to deal with and I wish John Caulfield and his players the very best of luck for the rest of the season.”
The Irish media reported that Newcastle had tabled a €100,000 offer for Murphy earlier this year.
