The assistant manager won't be underestimating Wigan at the DW Stadium tomorrow despite the fact the Latics haven't won a game since January 16th.
"Wigan are very organised under Martinez and he's got them trying to play football," said Lee.
"They've got pace about them all over the park and it'll be a game we'll have to be very, very careful in. We'll have to try not to get caught on the counter-attack, be organised, finish [chances] and not allow them a chance to come back at us."
