With Swansea City sat in third and Cardiff City in ninth, the South Wales derby on Saturday night will be one of the most important in years.
The Swans are just three points off second with a game in hand, and the Bluebirds are six points outside the top six. A win for either side will be huge for their quest in a return to the Premier League.
Steve Cooper's side come into the game off the back of a heavy 3-0 defeat to fellow Championship promotion contenders Bournemouth
Meanwhile, Mick McCarthy and his men will be looking for their first win in four games after two draws and a defeat.
Cooper could make two defensive changes for this South Wales Derby with Ben Cabango and Jake Bidwell both pushing for recalls.
Jordan Morris and Liam Cullen will both be missing Saturday's game and the rest of the season with knee and ankle injuries respectively.
Marc Guehi is an injury doubt after picking up a groin injury and faces a late fitness test to see if he can play any part for the Swans.
Centre-back Curtis Nelson will miss Saturday's game through injury, meaning the Bluebirds have limited options at the back.
Full-back Joe Bennett will be out for the remainder of the season after undoing successful surgery on his knee.
McCarthy will also be without Lee Tomlin and Jordi Osei-Tutu with the pair still struggling with injuries.
Swansea City (3-5-2):
Woodman; Cabango, Bennett, Naughton, Roberts, Fulton, Grimes, Hourihane, Bidwell, Lowe, Ayew.
Cardiff City (3-4-2-1):
Smithies; Sang, Flint, Morrison, Brown, Ng, Vaulks, Ralls, Murphy, Bacuna, Moore.
Ones to watch
After relegation from the Premier League in 2018, it looked like Andre Ayew would leave the club, but since then he has been a valuable asset to the club in their bid to return to the top flight. This season, he has been vital in their good form under Cooper.
The Ghanian international has scored 14 goals in 35 league appearances for the Swans, making him their top scorer. His dribbling and composure in front of goal are the two main reasons why they are in the position they are in. He needs to be kept under wraps at all times if Cardiff are to claim the bragging rights.
Cardiff took advantage of Wigan Athletic's financial situation and completed the signing of Welsh international Kieffer Moore for £2 million in the previous summer transfer window. Moore suits Cardiff's striker role down to a tee with his height and his ability in the air. The striker is a constant menace to any team in the league purely because of his aerial ability.
This season alone he has averaged 10.8 aerial wins per game which is just astonishing. The 28-year-old has also had one of his best goal-scoring seasons to date, contributing 16 goals and one assist for McCarthy's men. He offers more than just his goal-scoring though. His hold up play is one of the best in the league and allows the side to turn defence into attack with one long ball.
The two sides last met back in December with the Swans defeating the Bluebirds 2-0 at the Cardiff City Stadium with Jamal Lowe scoring a double.
The last meeting at the Liberty was last season, with loanee Ben Wilmot scoring the winner in a 1-0 victory for Swansea.
