The United defender could ease the Hammers' defensive woes.
Manchester United's Cameron Borthwick Jackson
Manchester United have reportedly told the 19-year old that he can go out on loan this season and Slaven Bilic has apparently ear-marked him as a target.

The Hammers have been left in a difficult scenario following a long-term injury to Aaron Cresswell and there are no other senior left-backs available at the club.
Sam Byram was deployed there as a makeshift option in their Europa League qualifier against NK Domzale last week but Bilic will not want to begin the Premier League season without a specialist in that position.

Borthwick-Jackson impressed at Old Trafford last season, appearing 14 times in all competitions, after the Red Devils suffered an injury crisis of their own.
The pacey fullback would be a useful addition to the Hammers’ squad and a loan deal makes sense considering that they just require a temporary solution.
Cresswell has been ruled out for up to four months so is unlikely to feature until the New Year and West Ham could do far worse than Borthwick-Jackson as a stop gap.
