Chelsea manager Enzo Maresca admits he is "worried" about playing on a much-criticised artificial surface in the semi-final of the Conference League.
The Blues face Djurgarden on Thursday evening on a pitch even the Swedish club's manager Jani Honkavaara described as "horrible" after a match against GAIS last week.
His criticism of the the 3Arena pitch has been echoed by Djurgarden's players and rival managers.
Work has been done to improve the quality of the surface by adding extra sand ahead of the upcoming match against Chelsea.
But Maresca, who has spent the last few days analysing Djurgarden by watching their last six matches, is aware the pitch could cause issues.
