Liverpool's controversial £20m star declared himself one of 'best in the world' and may soon be proved right

Lovren joined Liverpool for £20m in July 2014. He was signed after Luis Suarez left for Barcelona. Lovren's debut season at Anfield was difficult. The defender was criticised by fans for his poor performances. Following the sacking of Brendan Rodgers, Loven's performances improved. In April 2016, he scored the winner against Borussia Dortmund in the Europa League quarter-finals. He declared himself one of the best defenders in world. Liverpool are in contention to win the Champions League. They play Manchester United on Sunday. It will be interesting to see if Lovens can add to his impressive form.
