Sheffield Wednesday are in superb form right now, with Darren Moore's side boasting a long unbeaten run.
In all competitions the streak is currently at 14 games, since a penalty shoot-out defeat to Southampton in the EFL Cup on November 9 last year. In the league the run is even longer, with last weekend's win over promotion rivals Plymouth making it 16 without loss for the Owls in League One.
Tuesday night sees attentions switch to the FA Cup, with a fourth round replay away at Fleetwood. It will be the fourth game between the two sides in little over a month.
