The right-back had been linked with a move to The Hawthorns, as well as Aston Villa.
Mathieu Debuchy's hopes of earning a place in France's squad for Euro 2016 appear to be in the hands of Roma, after West Brom boss Tony Pulis confirmed that he has no intention of signing the Arsenal defender, The Sun reports.
The 30-year-old is hoping to negotiate an exit from the Emirates this month after it became clear that Hector Bellerin is Arsene Wenger's preferred choice at right-back. And with the European Championships just around the corner, Debuchy - who has not played for his country since September - is hoping to find a club that can offer him the game-time he craves to convince Didier Deschamps that he is deserving of a place in the side.
While Aston Villa were interested in a move, The Sun reports that Debuchy is not so keen on joining Remi Garde's squad given their hopes of avoiding relegation look extremely bleak.
And while the former Newcastle man may have hoped that the Baggies were set to offer him the opportunity to remain in the Premier League, Pulis has quashed any speculation surrounding a potential deal (via The Sun).
"I've not said a word to Arsenal and Arsenal have not said a word to me, so that's a definite no," he stated when asked about the move.
Having impressed since he arrived in England in 2013, playing at The Hawthorns would have provided Debuchy the chance to stake a claim for a place in the French squad in a division he is already proven in, which arguably would have made his task much easier.
However, with the Baggies now apparently out of the running, Debuchy will be hoping that Roma's interest materialises into a bid before the end of the month, otherwise he faces the prospect of missing out on the tournament altogether.
