Manchester United will back Jose Mourinho with another massive transfer budget this summer.

The Sun says the 53 year old has already spent almost £150M on world record buy Paul Pogba (£89.3M), Eric Bailly (£31M), Henrikh Mkhitaryan (£27M) and free transfer Zlatan Ibrahimovic.

But he also has plans to sign Athletic Madrid's Antoine Griezmann who is expected to cost £100M.

His targets also include Tiemoure Bakayoko who will face Manchester City with Monaco in this week's Champions League clash and Benfica's Victor Lindelof.

Mourinho – who ironically predicts that the transfer market will get even crazier – could spend £200M this summer.

Yet United now believe they have the extra financial strength to keep bringing in top new talent.

Over the next five years including Mourinho's increased salary the investment in restoring the club to the very top could reach that incredible £1 BILLION figure.
