"No disrespect to Wigan but if you want to challenge for the title then you need to be winning games like this," said Finnan.
"We had taken the lead as well and we thought we were going to go on and win the game.
"The goal we scored was a good one and it is obviously frustrating and really disappointing that we didn't win.
"The first goal is always important, especially when a team sits back a lot because it can be hard to break them down.
"So when you get that first goal you think you will go on from there but we didn't do that and they came back into the game.
"After Titus [Bramble] scored we had one or two chances but we didn't really look like we were going to score and overall it is disappointing.
"We have players who are capable of scoring goals but sometimes they just don't go in and it was the same against Man City but we definitely have the players there.
"We've slipped up at home and it is going to be really difficult but we've got to look to the 18 games we've got left and try to do our best."
