Sunday's mid-table clash between Sunderland and Fulham at the Stadium of Light (14:00 GMT) brings together two sides experiencing slumps in otherwise solid seasons, both buoyed by progress to the FA Cup fifth round.
Sunderland's 1-0 defeat against Liverpool in their last league fixture was their first loss at home all season, having won seven of their previous 12. It was the longest unbeaten home start to a top-flight campaign by a promoted side since Nottingham Forest went the entire 1977-78 campaign without defeat.
Black Cats have stopped purring
Head coach Regis Le Bris made six changes for their cup success against Championship strugglers Oxford United and it will be interesting to see if the Frenchman thinks anyone he drafted in made a good case to start this game as he looks to arrest a decline in the Black Cats' form.
Since victory in the Tyne-Wear derby on 14 December, the Mackems' only league wins have come against Crystal Palace and relegation candidates Burnley, a run which has seen them drop from seventh in the table on New Year's Day to 11th.
Le Bris's side have lost four of their last six league games, as many as they had in their first 20 this season. Successive defeats to Arsenal and Liverpool marked the first time they've lost consecutive league games this term.
Chukwueze does it
Having been in the best form of their Premier League lives throughout December and January, Fulham are another side having a wobble, with three losses on the spin leaving them 12th in the table, one place and two points below Sunday's opponents.
Marco Silva's side have struggled on the road this season, with only the bottom two, Wolverhampton Wanderers and Burnley, having suffered more away defeats than Fulham's eight.
Most of the plaudits for the Cottagers' success this season have gone to Harry Wilson and Raul Jimenez, who scored the winner in the reverse fixture in November. Kevin's recent contributions have also caught the eye, but there's another attacker adjusting to life in west London who shouldn't go unheralded.
Winger Samuel Chukwueze has endured a stop-start Fulham career since joining on loan from AC Milan in September, largely due to his involvement in the Africa Cup of Nations with Nigeria.
Despite his limited time on the pitch, his contributions have been notable. Of all players to have played 500-plus minutes in the Premier League this season, only Erling Haaland is averaging a goal involvement more frequently than Chukwueze.
Fulham, who are aiming to complete the league double over Sunderland for the first time since the 2002-03 campaign, have a good recent record against promoted teams, although their 12-game unbeaten run in such fixtures came to an end with a 1-0 defeat at Leeds United in January.
