The former Leeds United and Leicester City star has completed his medical and is now set to sign from St Etienne.
The Ivorian scored 17 goals last season for the Ligue 1 side, and is said to be costing Bournemouth £7 million as per the Mail, making him the club's second highest signing ever.
He was an impressive performer at his previous clubs in England, and has already spent a short loan spell at the Cherries when he was a teenager - scoring 9 times in 35 games for the then League One side. He will be joining fellow winger Christian Atsu, who is on loan from Chelsea, on the south coast.
Gradel was a fan favourite at Elland Road, after the winger scored a superb 18 goals in 44 appearances in his final season in 2011-12, not to mention receiving a call up to the Ivory Coast national team for the first time that year.
But the Whites only managed to finish in seventh spot in the Championship, outside of the playoffs, and therefore it was predictable that top tier sides would come sniffing around a player who had proved himself a major talent in the making during his time at Leeds.
Gradel ended up leaving the Yorkshire side having made 85 appearances and scoring 25 goals, and he went on to play for his country at the World Cup in Brazil last summer.
Now after a hugely impressive final season in France, which means the 27-year-old has 31 goals in 114 games for Les Verts, it looks like he will be returning to England to terrorise Premier League defences for the first time, with Sky Sports saying a deal is likely to be sealed in the next 24 hours.
