Jose Mourinho has called for Manchester United's transfer chiefs to up their game in the final days of the market, claiming the Red Devils will face a 'difficult season' if they do not make more signings.
Premier League champions Man City - who finished 19 points ahead of United last season - have added Riyad Mahrez to their ranks and hope to add an additional holding midfielder, while Liverpool's signings of Fabinho, Naby Keita, Xherdan Shaqiri and Alisson have added huge amount of depth to a side that reached the Champions League final.
For Mourinho's part, Brazilian midfielder Fred has come in alongside Portuguese youngster Diogo Dalot, while Lee Grant arrived to take up a position as the Old Trafford side's third-choice keeper.
