Arsene Wenger says the purchase of Thiago Alcantara by Jurgen Klopp is the root of the problems at Liverpool.
The former Barcelona midfielder joined in the summer from Bayern Munich for £20m with much expected of a player who has on numerous titles in his career.
But it hasn't quite gone to plan with Thiago winning only five of the 14 matches he has played this season, leading to pundits and fans questioning his performances.
And Wenger admits he feels sorry for Klopp as the Liverpool boss' attempted improvements have had an adverse effect.
Speaking on beIN Sports, Wenger said: “Thiago, for me, shows the typical problem of a manager.
"Liverpool were very hungry and aggressive in midfield. As a manager, you think, 'now I want to make the team better and I'll get a technical player'.
"When you get a technical player, you lose the aggression in midfield and you destroy a little bit of the strength of Liverpool.
"They have certainly less capacity today to win the ball back and they suffer a little bit more. So sometimes when you want to improve the team, you take something away from the team."
