Both sides have played the same number of games, but Saturday's opponents Sunderland have four games in hand, and, should the worst happen on Saturday, they would go three points behind West Ham who are on level terms with Wigan but have played a game more.
"There are plenty of games left and we need as many wins as possible - we are definitely capable of winning a few on the trot," says Bobby.
"Since I have been here we have not lost - except the FA cup game - and we have to use that as a positive.
"Sunderland is going to be a tough game, though, and obviously they are on a roll at the minute - but it will be a long, bad journey home if we don't get anything."
Bobby scored the second on Tuesday evening in the 5-0 win over Wimbledon - their eighth successive defeat - and he says:
"I was delighted to get the goal though obviously a bit disappointed to come off - it was a bit of a precaution as my knee was hurting at the start of the game."
It made up to some degree for the frustration of the draw at home to Walsall on Saturday, and Bobby adds:
"Walsall came to us with a game plan and did well; you have to get a goal and once you do that it opens things up, which is what happened on Tuesday."
Was his disallowed 'goal' really offside against the Saddlers?
"I don't know; I haven't even seen the replay," he shrugs.
"But to come away with a lot of goals against Wimbledon meant the lads were happy - the opposition battled and have still got a good spirit."
Alan Pardew says of Bobby's contribution:
"Bobby scored a terrific goal but I thought he looked edgy; he has this club in his heart, and that's genuine, but I think he takes things too seriously sometimes - and that worries me.
"Once he got that goal, though, he looked a lot happier with himself and it was a cracking goal."
Had David Connolly not had a late strike unluckily - some say unfairly - chalked off for offside West Ham would have equalled the highest score against the Dons this season, a 6-0 win by Nottingham Forest in October - set up by two first half Marlon Harewood goals.
