KEY BATTLES

Collins was outstanding in goal at Ipswich on Saturday. He may have to be at his best again at Hillsborough against a strikeforce led by experienced 34-year-old striker Gregory who has 96 EFL goals. Gregory has scored twice against the Reds for Millwall and once for Stoke. He is likely to be partnered by Josh Windass who has netted twice for the Owls against the Reds.

They both struck on Saturday in the thrashing of Forest Green. Collins will need help from those around him such as Liam Kitching, who must keep his head in a feisty derby, and potentially Robbie Cundy who may return to the back three for this physical test with Jordan Williams back at right wing-back.

Darren Moore v Michael Duff

Moore had an excellent record against Duff as a player, winning three and drawing one of his league meetings against Burnley for Derby and Barnsley.

The former centre-backs both made the most of their talent, and got to the Premier League with a strong mentality and leadership qualities.

They met for the first time as managers last season, with Duff’s Cheltenham netting an injury-time leveller in a 2-2 home draw but losing 4-1 at Hillsborough later in the season.

Moore has had far longer to work with his squad and shape it in his mould, while he is thought to have a bigger budget.

There is a mutual respect between the pair but they will both be desperate to outwit the other in this derby.
