McLean came through the youth system at St. Mirren but it was Arbroath where he made a first team debut when he went to the Division Three club on loan. He made his debut for them in December 2009 in a 4-3 home defeat against Stirling Albion and, in total, made 23 appearances during his loan, culminating in the play off final against Forfar Athletic, which they lost 2-0.
Back at St. Mirren, he finally made his debut in the SPL in October of last year, coming on as a substitute in a 2-2 home draw against Hamilton Academical. Since, he's established himself in the team and in October of this year scored his first SPL goal, the winner at St. Johnstone.
October 2011 was a good month for the 19-year-old. It saw him named the SPL's Young Player of the Month. "It's my first award since I came into the first team, so it's great to pick t up so early and hopefully it's a sign of things to come," he said on hearing the news.
McLean is highly rated by St. Mirren boss Danny Lennon and he signed a new deal in October 2010 until the end of the 2013/14 season. His manager said that he's a good passer of the ball with his weaker right foot but can open a tin of beans with his left and added that he's a rare type of Scottish player who is always looking for a slide-rule pass.
Any move for McLean would have to wait until the transfer window opens in January, but meanwhile the Clarets have until a week on Thursday should they want to bring any players in on loan. That's Thursday of 'Next Week' which is apparently when Burnley do make their signings.
