Brazilian forward Kerolin has emerged as Manchester United’s main transfer target as the club look to replace Alessia Russo.
United, who have also shown interest in Kerolin’s international team-mate Geyse, are understood to be prepared to make a big offer for the North Carolina Courage forward.
But Marc Skinner’s side face competition from several top European clubs and United are yet to agree a fee.
The forward is one of the top scorers in the National Women’s Soccer League in America, with eight goals in 13 games and was named in the division’s team of the month for June.
