Liverpool fans had high hopes for Lovren when he signed from Southampton but his first season at Anfield has widely been regarded as a failure.
Lovren committed a number of errors, was part of a Liverpool team that has conceded just nine fewer goals than relegation-threatened Hull City and went through a spell of starting one league game in three months due to his poor form.
But the see things differently. Its annual study into the top five leagues in Europe concluded that the former Lyon defender is better than John Terry, Vincent Kompany and Gary Cahill.
Based on its six criterion of shooting; chance creation; take on; distribution; recovery and rigour, Lovren is the 12th best defender in Europe and top of the pile in England's top flight.
Paris Saint-Germain defender Thiago Silva is rated as the best centre-back in Europe, with Jerome Boateng of Bayern Munich and Barcelona's Javier Mascherano just behind him.
Despite being involved in a relegation scrap, Sunderland's Patrick van Aanholt is rated as the 15th best full-back in Europe, while Gael Clichy is third and Manchester United's Antonio Valencia fourth.
Chelsea's Cesc Fabregas is regarded as the best "defensive midfielder" on the continent.
Only James Rodriguez is rated as a better attacking midfielder than Chelsea star Eden Hazard. Swansea's Gylfi Sigurdsson makes the cut for the top 15, sitting in 14th place - 10 places above Manchester City's David Silva.
Messi is listed as Europe's best forward. The Barcelona star tops the strikers' list, followed by Cristiano Ronaldo and Luis Suarez.
Sergio Aguero is fifth and Diego Costa seventh.
