MILLWALL midfielder Liam Trotter believes that matches against Leeds United have become just as important as local derbies.
Trotter, who has scored six times in 16 starts for the Lions this season, says the Yorkshire side are in the same bracket as West Ham, Crystal Palace and Charlton.
The two clubs meet at The Den on Sunday lunchtime and the 24-year-old is under no allusions as to the importance of the game to the supporters.
"Leeds is a big game," he said. "Their fans are very passionate and very similar to ours. They always come down with a lot of fans.
"It has always been a good rivalry and a good game against them so we are all looking forward to it.
"It should be a good atmosphere. It will be a good day and we will be looking to carry on our good form."
Trotter believes the rivalry stems back to the League One play-off semi-finals in 2009, in which Millwall famously claimed a draw at Elland Road in the second leg to reach Wembley.
"It is like a local derby and that comes down to the fans," he said.
"We were both going for promotion at the same time so we are both on similar paths.
"The games against them in the last two or three years have been really enjoyable to play in."
