Manchester United have struck a £50m agreement to bring Chelsea and Brazil midfielder Andrey Santos to Old Trafford, with the deal now subject to a medical.

The transfer is structured as a £48m guaranteed fee with a further £2m in potential add-ons. As part of the arrangement, Chelsea will retain a 10 percent sell-on clause on any future transfer of the player.

Santos is set to undergo his medical with Manchester United imminently, paving the way for the move to be finalised.
