Manchester United have reportedly put their deal with Roma over Chris Smalling in jeopardy, after raising their asking price in the final days of the transfer window.
The two sides have been locked in negotiations and are hoping to get a deal in place before Monday's 11pm deadline.
But United now want over £16million for the former England international, according to the Calciomercato in Italy, which has put Roma's move in doubt at the last moment.
United's asking price is set to have shifted from £13.
