2) Shinji Kagawa (£17m)
Another player who has seemingly run out of time to prove himself at United, Japanese playmaker Shinji Kagawa is not in Louis van Gaal’s plans for next season and could leave if the club receive offers of around £17m. The 25-year-old had been one of the finest players in the Bundesliga during his time with Borussia Dortmund, prompting United to sign him back in 2012. Kagawa remains highly regarded by Dortmund’s fans and by several other big clubs around Europe, and could still have plenty of suitors this summer, despite his struggles to adapt to life in the Premier League.
