The English striker is bound to the club until 2022.
The 27-year-old striker progressed through the youth ranks of Wolves and Shrewsbury Town.
Gray came into prominence during his impressive spell with Hinckley United, bagging more than 30 goals in two seasons.
He further enjoyed success with Lutton Town and Brentford, where his eye-catching goal stats caught the attention of Burnley.
He played a part in the Clarets’ promotion push in his first season and also fared well in Premier League.
Prior to the last season, Gray signed for the Hornets and had moderate success. As far as this season is concerned, the English striker has bagged 9 goals and 3 assists across all competitions.
Why should the Gers move for Gray?
Steven Gerrard has fared decently in his first season at Ibrox, despite ending up with no title.
The Light Blues have been highly reliable in their goal-scoring prospects wit the help of Alfredo Morelos throughout this season.
And the Colombian’s lack of discipline on the field has seen him often getting red cards and suspension, which has become a growing concern for Gerrard.
Jermain Defoe remains the only back-up and he has failed to find is feet on occasions. Furthermore, he is bound to Bournemouth FC and also catching up with age.

Having said that, Gray would be a prolific option for the Gers to build a strong line of attack. The English striker can also play as a left winger, which would be an added advantage.
