The Premier League side are looking to strike a deal for an initial loan move in the January transfer window before making a permanent offer in the summer if the Costa Rican youngster impresses at the Hawthorns, with an £8 million fee being mooted.
However, Irvine faces stiff competition to land the highly-rated 22 year-old, with fellow Premier League side Everton as well as European giants Inter Milan, Juventus and Sporting Lisbon all eyeing up a move for the forward.
Campbell joined Arsenal in 2011 but spent three successive seasons out on loan, including a spell with Olympiakos last season. After rising to prominence with a goal-scoring display for the Greek side against Manchester United in last year’s Champions League, he went on to impress for his national side in the World Cup, before returning to North London in an attempt to break into the starting eleven.
That has not happened, and with only three appearances for the Gunners to date this season, he may be tempted by a move to West Brom to secure first-team action.
