Derby County take on Nottingham Forest next Friday, in what is shaping up to be a hugely important clash at Pride Park.
It makes sense, then, to reflect on the past, and more specifically, focus on those who have dared to play for both sides at some point in their career.
Jamie Ward scored 34 goals in 138 games for Derby during a four-year stay at Pride Park, but in 2015, he made the journey across the A52 and signed for Forest on a free transfer.
Forest were under a transfer embargo at this time, meaning that Forest could only bring in players on free transfers.
Who has done more of these 15 things out of Derby and Nottingham Forest?
Ward scored two goals in 31 Championship appearances in his first season at the City Ground, chipping in with five assists.
The following season, he failed to make an impact under Philippe Montanier, subsequently joining Burton Albion on loan for the first six months of the 2016/17 campaign.
Loan spells at Cardiff City and Charlton Athletic followed the season after, and in September 2019, his time at Forest came to an end for good, with the attacker joining Scunthorpe United on a free transfer.
So what is Ward up to nowadays?
Well, the 34-year-old is back in his hometown of Birmingham, playing for Solihull Moors in the National League.
Ward has scored two goals in 14 appearances for James Shan’s side this season, with Moors sitting in mid-table, hoping to ignite a push for the play-offs.
