Manchester United are reportedly planning to hand manager Jose Mourinho a significant January war chest in order to improve his squad.

Mourinho was frustrated by the club's lack of investment during the summer - particularly in defensive areas - and reports have suggested that the board were once again reluctant to splash the cash in January due to concerns over the manager's long-term future.

However, The Mirror claims that United do plan to back Mourinho when the transfer window reopens, despite seeing the club's value fall by more than £300m.

The Red Devils' latest financial results show that the club's share price has fallen to its lowest level since 2013, plunging to £14.21 per share this week compared to the July high of £21.45.

Executive vice-chairman Ed Woodward is understood to have ensured investors that the club still have the financial muscle to spend big in the transfer market, though.

Mourinho is known to be keen on defensive reinforcements, with the likes of Harry Maguire, Toby Alderweireld and Diego Godin once again being linked to the club.
