Aitor Karanka's plans to strengthen his squad have suffered a blow after 'Boro saw two large offers rejected. Firstly for long-term target Jelle Vossen of Genk, a player which they tried to sign back in January. They have also been trying to sign Adam Clayton from Championship rivals Huddersfield Town.
Middlesbrough's only signing so far this summer is that of Tomas Mejias from Real Madrid. The 25-year-old goalkeeper had been on loan at the club since February and has now joined on a two-year-deal with the club.
After the departure of Marvin Emnes to Swansea City, a striker would be high on Karanka's list. The future of Lukas Jutkiewicz also remains in the balance following his loan with Bolton Wanderers last season. Vossen was targeted in January and 'Boro saw a bid rejected for the Genk striker back then.
They have since returned and the bid is thought to be in the region of £3 million but this has also been rejected. Genk had promised Vossen that they would listen to bids for the 25-year-old but given they rejected a bid from Rubin Kazan of £5.6 million they had no interest in letting their star man leave for much less.
Genk chairman Herbet Houben said "There was a more lucrative offer from Russia [in January] at which point we agreed with Jelle to cooperate, but only at that level or similar, but there has been no bid like that yet."
"I firmly believe in the next few weeks and months, better offers will come."
A target closer to home is that of Adam Clayton who shone for Huddersfield Town last season. The former Leeds United and Manchester City player stood out for Mark Robins' side last season but that may have had something to do with his huge beard which he died blue and white for the last game of the season.
Sky Sports understands 'Boro tabled an offer of over £1million, but Town were quick to reject the bid as they want the player to remain at the club. Brighton are also thought to be interested in the 25-year-old so The Terriers may find it hard to keep hold of him.
