Derby County v Southampton
Frank Lampard's Derby will look to cause another cup upset when they play host to Premier League Southampton on Saturday.
The Rams have already knocked Manchester United out the League Cup this season, while Lampard's men are currently in the Championship play-off zone after losing just one of their last six league games.
Southampton, meanwhile, have not won any of their three matches post-Christmas (two defeats and one draw) and occupy the final relegation spot in the Premier League.
Ralph Hasenhuttl has been boosted by the fact defender Matt Targett is available after recovering from a thigh problem although the new Saints boss faces an anxious wait on three key players.
Danny Ings limped out of the Chelsea game in midweek with a hamstring problem, while Ryan Bertrand and striker Michael Obafemi are also doubts due to back and hamstring problems respectively. Pierre-Emile Hojbjerg is still missing through suspension, while Maya Yoshida is away on international duty with Japan at the Asian Cup.
The last time the two sides met in a competitive clash was in the Championship in 2012 when Saints won 4-0 at St Mary's, with Southampton unbeaten in their last five meetings.
