Levante have rejected an offer for Ghanaian winger Riga Mustapha.

Five Premiership clubs watched the Ghana-born wide-man in action at the weekend as he scored two in a win over Racing Santander.

Manchester City, Wigan, West Ham, Portsmouth and Middlesbrough all watched Mustapha and one of them is now believed to have lodged an offer.

Reports reaching Homebase Media say Middlesbrough, via an agent working on their behalf, lodged a €2million (£1.3million) bid - although it remains to be seen which club indeed made a firm approach.

One thing which is clear is that the offer was not acceptable.

"The offer is insufficient," president Pedro Villarroel told the reporters.

Reports suggest Levante want €4million (£2.7million) before they would consider letting Mustapha leave.
