Man Utd chiefs have one reason for refusing Chelsea transfer bid for Dean Henderson

Both sides had troubles at the back this season, and have their own problems in the goalkeeper position. 

Lampard has dropped Arrizabalaga multiple times this season and has been tipped to move on from him this summer, while De Gea has made a series of blunders throughout the campaign.  

However, with both goalkeepers locked into long-term contracts on large salaries, it could be difficult for either team to change their first-choice stoppers. 

And Chelsea hero Mark Bosnich believes Lampard could opt to stay with Arrizabalaga and give him another try next season.
