Manchester United have reportedly been left "stunned" by Newcastle United's £50 million valuation of midfielder Sean Longstaff.
According to ESPN FC's Rob Dawson, United's chief negotiator, Matt Judge, met with Newcastle managing director Lee Charnley at the weekend, but no formal bid was submitted as the Red Devils value Longstaff between £18 million and £20 million.
United's £50 million signing of Aaron Wan-Bissaka from Crystal Palace has prompted Newcastle to demand the same for Longstaff, and the Red Devils may have to end their pursuit as a result, added Dawson.
Wan-Bissaka and Longstaff are both 21, but the former has 42 Premier League appearances to his name compared with the latter's nine.
