Reports have suggested the Baggies are set to sign the Republic of Ireland star in a £7million deal.
“He’s a top, top boy,” said Cox on Sky Sports News.
“I know him from Reading when he came in with Kevin (Doyle) and Stephen Hunt.
“I think, for me as a player, he would be a good addition to the squad and hopefully he comes in and produces exactly what he did last year.
“Competition is good and healthy, and it makes players be at the top of their game day in, day out, week in and week out.
“I’m quite happy to fight for my place, and some people might be fighting for places on the bench. If I’m one of those players, then great, it will bring the best out in me.”
