Boro make official offer for Wigan midfielder
Boro are interested in signing the 28-year-old midfielder from Wigan Athletic.
Morsy was left out of the Wigan squad for their EFL Cup clash against Fleetwood Town on Saturday, amid speculation he was close to securing a move to Boro.
The 28-year-old made 44 appearances in all competitions for the Latics last season, scoring three goals and assisting three times. He was also named Wigan's Player of the Year.
Morsy is one of the players that Wigan Athletic are set to sell following their relegation to League One.
Championship rivals Stoke City and Sheffield Wednesday have been linked with the midfielder, along with Premier League sides Crystal Palace and Brighton & Hove Albion.
