As Real Madrid prepare to launch another bid for the goalkeeper, with United demanding a fee in excess of £60 million, Ander Herrera has shown his determination for his fellow country man to stay at the Premier League outfit.
'Maybe I am a bit boring on this, but I always say the same', the midfielder told 'Cadena SER', 'David is one of the few keepers who give you points over the course of a season'.
Jose Mourinho's side will face the Champions League holders on July 23 with Zidane's team set to submit a bid for the goalkeeper shortly.
Ander Herrera believes the Red Devils should not accept an offer for his compatriot: 'I prefer to have him with me, so I will do everything possible to have him here'.
