Pick of the stats: Derby County v Sunderlandpublished at 10:50 21 January

Derby County welcome Sunderland on Tuesday as pressure mounts on Rams manager Paul Warne (19:45 GMT).
Derby have not won a league match in their past four league games to leave them only one point clear of the bottom three, while Sunderland's Friday fixture against fellow promotion contenders Burnley ended goalless.
Derby had success at Pride Park at the start of the season but the Rams have only won two of their past eight home games, whereas the Black Cats have only lost two of their past 10 away games.
Derby are winless across their past 13 league games against Sunderland (D5 L8) since a 1-0 win at Pride Park in February 2001 in the Premier League.
Sunderland are unbeaten across their past six away league games against Derby (W4 D2); the Black Cats' longest ever such run in this fixture.
Derby have won two of their seven Championship games this season that have taken place in midweek (Tuesday, Wednesday, Thursday), losing three of them (D2); they did, however, win their last such game at home against West Brom 2-1 in December.
Sunderland have won all four of their league games against newly promoted sides in the Championship this season, scoring eight goals and conceding only once.
Derby boss Warne has won one of his previous five Football League encounters with Sunderland (D2 L2), losing each of the past two league meetings by an aggregate score of 0-5.
