Manchester United have gone cold over their bid for Gremio starlet Douglas Costa.

The Times says United have cooled their pursuit of Douglas Costa, the Brazilian forward, amid frustration at the exorbitant demands of Grêmio.

United opened negotiations with Grêmio last month, but discussions are unlikely to resume this summer unless the Brazilian club dramatically reduce a prohibitive £20 million asking price for the teenager.

The number of agents involved in the proposed transfer is another factor that has led the club to walk away from the negotiating table.
