West Brom winger missed pre-season and has barely been involved this campaign
Chadli didn't feature in pre-season as he refused to attend West Brom's training camp in Austria, while he was heavily linked with a move to Swansea City only for the deal to fail to materialise.
Pulis stressed that Chadli hasn't felt sharp in the games that he has played so far this campaign.
As reported by the Express and Star, Pulis said: “I spoke to Chads and he feels 60 per cent, he doesn’t feel 100 per cent, and you can understand that.
“He has missed the pre-season, he’s had all that speculation with Swansea that affected him during the first couple of weeks of the season, and there are people like that who have had injuries.
“The two games that he’s played in he’s not felt sharp."
Chadli scored against Leicester City in his first Premier League appearance of the season, while he also featured against Southampton but he was an unused substitute for the games against Manchester City and Huddersfield Town prior to the international break.
Last night Chadli completed 84 minutes as Belgium beat Japan 1-0 and he will hope to be involved in some capacity when West Brom return to action on Saturday with a home game against Chelsea.
West Brom have lacked creativity and directness at times this season and Chadli, who possesses much pace and trickery, could help to solve that problem if he was to feature regularly.
