Derby County manager Wayne Rooney faces a selection headache for the visit of Nottingham Forest with Lee Gregory boasting a terrific record against the Reds.
The Rams lined up with three at the back in the 2-0 win over Huddersfield Town.
But despite leading 1-0 at half-time, Rooney told reporters after the game how he got his tactics wrong and he rectified that at the interval with a questionable double change.
Gregory, who started the game, came off while controversially goal scorer George Edmundson was also hooked as Kamil Jozwiak and Martyn Waghorn entered the field.
Derby played better in the second period, and Rooney may well feel the 4-3-3 with Jozwiak and Waghorn either side of Colin Kazim-Richards provides the best balance.
But Gregory’s record against Forest can’t be ignored ahead of the encounter.
The former Millwall man has scored five goals in his last seven encounters with the Reds, including one at the City Ground on the final day of last season.
Forest needed just a point at home to Stoke City to reach the playoffs, but instead they fell to a 4-1 defeat which saw Swansea City leapfrog them into sixth on goal difference.
Gregory also scored in Stoke’s 3-2 home defeat to Forest earlier in the season.
To get Gregory on, Derby would have to move to either three at the back or a 4-4-2, both of which Rooney has deployed depending on the opponents in recent weeks.
Victories over Middlesbrough and Wycombe Wanderers occurred recently with Gregory starting, but in both encounters the Rams played a much more direct style of play.
Rooney may feel this will be another scrappy game and opt for a similar direct approach, but the improvement against Huddersfield may persuade the Rams boss to stick with a winning team.
