Chelsea new boy Noni Madueke has been hailed as a "mentality monster" by a former coach after his £30m switch.
The England U21 star has made the move back to London, the city of his birth, from PSV Eindhoven and has been talked up by his personal skills coach. Saul Isaksson-Hurst, has worked with Madueke during the last two summers and gave him a glowing review ahead of his Stamford Bridge bow.
Chelsea have continued to splash the cash under Todd Boehly and have already spent over £100m in January. Madueke will bolster an already star-studded attack but, at just 20 years of age, has been tipped for major improvements due to his impressive attitude.
