Stoke City striker Tuncay Sanli is chasing former club Middlesbrough for unpaid fees.

The Daily Mail says Tuncay claims Boro, his employers between 2007 and 2009, still owe him a total of £544,677 in unpaid image, sporting and economic rights.

It is claimed Boro agreed to pay him a total of £3,544,677 for those rights when he first joined them, but have so far paid £3m.

Tuncay's relationship with his old club is further soured by a second High Court lawsuit against Middlesbrough in which his agent is claiming £400,000 plus interest in unpaid fees.

It is alleged that Mikel Eiguren Arano has only received £800,000 of an agreed £1.2m package for his services in handling Tuncay's free transfer from Fenerbahce in the summer of 2007.
