Alex Neil says Sunderland’s trip to Sheffield United will be their “biggest test” since winning promotion to the Championship (Match Betting – Sheffield United 4/5, Draw 13/5, Sunderland 4/1).

The Black Cats are unbeaten in the league this season but were taught a lesson on Saturday, squandering a 2-0 lead to draw 2-2 at Queens Park Rangers and Neil has admitted the result showed his players how much of a “chess match” games are in the second tier.

Meanwhile, the Blades bounced back from an opening defeat to Watford, before beating Millwall and drawing at Middlesbrough.

United (5/2 Promotion) boss Paul Heckingbottom has lamented that he is without nine players for the game at Bramall Lane.

However, even considering that, Neil says the host’s depth means they will push his side to new limits.

“This will be our biggest test to date, without a doubt,” he said. “What they have more than anything, Sheffield United, is experience.

“Last year they were in the Championship, but the previous two years they were in the Premier League. They have come down from the Premier League and with their parachute payments, they will expect to get out of this league, and they made the semi-finals of the play-offs last year.”

The game in South Yorkshire is one of three 20:00 kick-offs in the Championship on Wednesday, while the 19:45 kick-off sees Stoke take on Middlesbrough.

Boro are still to win this season, while Stoke’s sole victory came on their own patch, beating Blackpool 2-0 on August 6 (Match Betting – Stoke 9/5, Draw 11/5, Middlesbrough 17/10).

Meanwhile, leaders Blackburn have a chance to make it four wins from four and extend their lead at the top of the table when they take on former manager Paul Ince and his Reading side (Match Betting – Reading 23/10, Draw 12/5, Blackburn 5/4).

One issue for Rovers is that with rumours of a move to Everton or Nice abound, Ben Brereton Diaz could miss out, meaning Sam Gallagher (12/5 Anytime) could lead the line.

Finally, and one of the season’s surprise packages, Cardiff will be eyeing a third win against an underwhelming West Brom side (Match Result – West Brom 3/5, Draw 3/1, Cardiff 5/1).

The Baggies are 11/4 to be promoted but have taken just two points this season. Meanwhile, the Bluebirds have won twice, although their sole defeat was on the road at Reading.
