The story says that Manchester United are on the lookout for attacking reinforcements this month as Mourinho looks to give his team the best possible chance of catching Manchester City in the race for the title.
Mourinho feels that Zlatan Ibrahimovic's injury setback has left him short on back-up options for Lukaku as he prefers to play Marcus Rashford and Anthony Martial out wide.
Lukaku has started all but one of their Premier League and Champions League games this season, scoring 15 goals in total, with Jose Mourinho having very few options to rotate the £75m striker. Ibrahimovic is not expected to extend his stay at Old Trafford into a third season, with speculation earlier this week suggesting he could be allowed to leave the club before the end of his contract in June to sign a lucrative deal in the U.S. or China.
Manchester United have identified Javier Hernandez and Jamie Vardy as targets as they consider signing a striker in January to support Romelu Lukaku.
Manchester United have enquired about the possibility of re-signing Javier Hernandez as Jose Mourinho looks to bolster his strike force, according to reports in the British media.
Former United striker Hernandez is surplus to requirement at West Ham and stands as the easiest option, with new Hammers boss David Moyes reportedly looking to offload the Mexican this month.
Vardy likewise guarantees goals but Leicester would be highly reluctant to let their main goal threat leave, you sense.
United's third target is Hernandez, a man the Red Devils know well after he spent five years at the club before being sold to Bayer Leverkusen in 2015.
