Chelsea coach Enzo Maresca admitted to being worried ahead of his team's meeting with League One or third division team Lincoln City in the third round of the English League Cup at LNER Stadium.
Maresca admitted that he was worried because he was afraid that his team would underestimate Lincoln City, which could result in defeat.
"Personally, I prefer playing against Premier League teams rather than League One teams because these are the games I worry about the most," Maresca said, as quoted on Chelsea's official website on Tuesday.
"Sometimes you can take things for granted, and football is still football. That's something we have to avoid," he added.
Chelsea are currently in sixth place in the Premier League table, while Lincoln City are currently in third place in the League One table.
