Halliday scored 16 goals in 23 games for Livingston last season
Championship side Middlesbrough have signed winger Andrew Halliday from Scottish Division Three champions Livingston for an undisclosed fee.
Halliday, 18, has agreed a three-year deal at the Riverside, having played a key role at Almondvale this season with 16 goals in 23 games.
"I'm really excited about joining Middlesbrough and delighted the contract is all sorted," Halliday said.
"This is a club that has produced so many good youngsters over the years."
Halliday added: "It helps that there is already a big Scottish contingent at the club and I know I am going to feel at home straight away.
A major reason why I wanted to come here was because this is a club that develops players
"I came here for a training week earlier in the season so I was able to see the set-up at first hand. It also gave me the chance to meet the players, so I have a bit of a head start in that respect."
With Adam Johnson's departure to Manchester City during the January transfer window, Boro boss Gordon Strachan had a vacant left wing berth to fill, and Halliday is keen to emulate the England hopeful in progressing at the club.
"I will be doing all I can to win a first-team place here. A major reason why I wanted to come here was because this is a club that develops players.
"Players like Stewart Downing and Adam Johnson have really flourished here. Although people describe me as a winger I often get mistaken for a striker because of my record this season.
