Manchester United have made a contract offer to Eintracht Frankfurt goalkeeper Kevin Trapp.

Trapp is viewed by United as ideal cover for David de Gea.

Bild says United have offered Trapp a four-year deal - which he is receptive to.

Some details still need to be ironed out, but the experienced keeper is open to the move.

A fee with Eintracht Frankfurt will also have to be negotiated.
