Manchester City and Manchester United will once again vie for Premier League supremacy this weekend, with both sides in action on Sunday afternoon.
Roberto Mancini's league leaders face a potential banana skin away at Swansea City, who have already beaten Arsenal and impressed against United at the Liberty Stadium this season.
Three points for the Swans may be could enough to carry them back into the top half of the table, but City will provide the sternest of examinations for the Welsh club.
Manchester United, meanwhile, are in action at Old Trafford against West Brom, aware that they must focus on winning their remaining fixtures rather than hoping City slip-up somewhere along the line.
The Baggies travel to Manchester on quite a run, having won their last three games, including the prized scalp of Chelsea last weekend, which led to Andre Villas-Boas losing his job.
As far as United are concerned, they must win if they have any hope of climbing to the summit of the table, but can only realistically do so if City lose in Swansea.
