Thomas Tuchel warned Chesterfield to prepare to face his multi-million pound strikers as the European champions meet the National League leaders in the FA Cup.
Both sides have been hit by injuries and Covid absentees in recent weeks, and Tuchel admits he will look to rest some first-teamers and involve younger players but is also keen to get Timo Werner and Romelu Lukaku back into a rhythm after missing so much action.
'We want to use the match to get some minutes into the guys who desperately need it and want it, like Timo,' said Tuchel, as he weighs this tie against three games in seven days against Tottenham, Manchester City and Brighton, starting on Wednesday.
