The 32-year-old was keen to stay and fight for his place, but Roy Hodgson has apparently told him that he does not figure in his plans.
The report claims that Tony Pulis is leading the race for his signature. Clubs in the EFL can sign players on loan which means Boro will have to sign Puncheon – who is on £35k-per-week wages – on loan.
With that in mind, Leeds should make a move for him and challenge Boro for his signature.
