James Forrest lauded Martin O'Neill after Celtic's interim boss guided the club to a historic double in a rollercoaster season, and says whatever the manager decides next will be met with widespread approval. An impressive nine-game winning run as the season drew to a close saw Celtic win the Premiership title last week with a thrilling 3-1 home win over Hearts. Forrest, 34, who won his 28th medal for Celtic on Saturday, a club record, singled out O'Neill's ability to win over all members of the squad quickly.
