Ralf Rangnick has revealed that he has turned to sports physiologist Sascha Lense to improve Manchester United 's mentality.
The Red Devils have been 1-0 up in their last three matches but failed to win any of them, leading to scathing criticism as they battle to end the season on a high.
Rangnick, whose period as interim manager runs until the summer, is busy searching for ways to turn United's fortunes around and has now called on to trusted confidant Lense.
