The Spain No.1 came close to leaving Old Trafford in 2015 and there are fears the move could materialise this summer
When David de Gea somehow kept out Luis Muriel's header shortly before half-time in Manchester United's Champions League visit to Sevilla last week, it was a familiar collective sigh of relief which was heard on the away terraces.
Not only had he done similar moments earlier to deny Steven N'Zonzi, but the Spaniard has become recognised as the world's best goalkeeper on the back of countless such interventions over the past five years.
Having struggled during his early months at Old Trafford, De Gea has been United's most consistent player since the retirement of Sir Alex Ferguson brought about greater pressure on the Red Devils' goalmouth on a weekly basis.
