Ahead of the Sky Blues' trip to Bramall Lane, we look at three players who have played for both sides...
Coventry City face Sheffield United in League One on Saturday, with a number of players playing for both sides over the years.
Here are three front men who have played for both the Sky Blues and the Blades, including one of the club's stars of the Premier League era...
PETER NDLOVU
With the Sky Blues from 1991-1997, Ndlovu had the best spell of his career with City in the Premier League as he became one of the stars of the Sky Blues' Premier League era.
The Zimbabwean international scored some memorable goals for the Sky Blues, including a hat-trick at Anfield in 1995, becoming the first opposition player to net three goals at Anfield since 1961.
He scored plenty more goals also spent time with United between 2001-04, before leaving them with 25 goals in 135 league games.
SHAUN MILLER
Striker from last season Miller was released from the Blades in 2014/15 and signed for the Sky Blues on a free transfer.
He made 28 league appearances and netted four times for United but his time at Bramall Lane was affected by injury.
He started his career at Crewe Alexandra and now plays in League Two for Morecambe following his release from City in the summer.
PAUL FURLONG
Furlong had a long playing career which lasted between 1986 and 2012. He played for City for just a year between 1991-1992, where he was brought to the club by Terry Butcher.
He netted four goals from 37 league games before moving to Watford.
His spell with Sheffield United came when he was at Birmingham City in 2002 - he was loaned to the Blades and made four appearances, netting twice.
