When Wigan take on Everton this Saturday, it sees two of the most highly rated managers in the country go head-to-head.
Wigan's form at the end of last season was, for lack of a better word, astonishing.
They looked dead and buried towards the end of February, but somehow, Roberto Martinez managed to guide them to seven wins in their last nine games, including wins against Manchester United and Arsenal, to make sure they stayed up.
In Ali Al-Habsi they've got a top-class keeper who makes save after save to keep his team in games that they should, by all rights, lose.
Scoring goals has always been a problem for Wigan, but in Arouna Kone, they seem to have found a striker with strength and pace who knows where the goal is.
Everton have been simply outstanding this season.
David Moyes has assembled probably his strongest ever squad on a very tight budget, but as always, his players give everything for their manager and right now, they're reaping the benefits of it.
Players like Marouane Fellaini, Steven Pienaar, Kevin Mirallas and Nikica Jelavic (among others) look unplayable at the moment.
If it wasn't for a poor refereeing decision in their game against Newcastle a couple of weeks ago, when they were denied a goal that was clearly onside, Everton would have five wins from six and nobody would complain.
The players are a credit to their manager, who is a top-class coach, and if Norwich can somehow take all three points against Chelsea, and Everton win at Wigan, Moyes will be sitting proudly at the top of the Premier League.
