West Brom look to be leading the race for the West Ham and Crystal Palace target.
It is stated that the former West Ham, Newcastle and Chelsea man will command a £10 million transfer fee - equalling the club record set last summer with the signing of Brown Ideye - and roughly wages of £70,000-per-week.
The £10m fee is said to be the lowest Besiktas will accept for Ba, having already sad yes to an offer from Chinese outfit Shanghai Shenhua, but the Senegalese international is only keen on securing a move to England.
The Baggies now look to be pushing ahead with their offer for Ba, having long held an interest in the 30-year-old.
Along with Crystal Palace and West Ham, the Baggies have been one of three Premier League clubs linked with making a move for Ba following his impressive season in Turkey.
The Sun claimed that West Ham boss Slaven Bilic wanted to link up with his former striker at the Boleyn Ground, whilst Eurosport suggested that Crystal Palace are keen on signing him, with Alan Pardew at the helm.
However, the Baggies look to be leading the race for his signature, having made official moves to sign him, and it remains to be seen whether West Ham or Palace respond to West Brom’s move by opening their own talks with Besiktas in the coming days.
