St Mirren are holding talks with Leon King after the centre-half was freed by Rangers. The 22-year-old is a key target for manager Craig McLeish, but the club have to bolster other positions first. St Mirren are set to win the race to sign 20-year-old Queen's Park centre-half Henry Fieldson on a free transfer, according to Pete O'Rourke. The potential signings come as St Mirren look to improve their league standing, currently 10th in Premiership with 30 points from 33 games, and a recent form of WDDWL. With a goal difference of -21, having scored 27 and conceded 48 goals this season, St Mirren need to strengthen their defence to compete with the likes of Heart Of Midlothian, who are 40 points ahead in the title race. The club's focus on signing new players is a clear indication of their intent to move up the league table, and with the right signings, they could make a significant impact in the remaining games.
