Wolverhampton Wanderers visit the John Smith's Stadium this weekend to face Huddersfield Town in a top-of-the-table Championship clash.

Town are unbeaten in four league outings this season - with three wins under their belt - and Wolves boast a record of two wins and two draws in the second tier.

Both sides could be looking at surprising promotion pushes should their league form continue in the same vein, so a point could prove vital for both clubs to keep the momentum going.

Here we have a look at five big questions that will be answered in the weekend match-up.

Danny Ward saved Dwight Gayle's penalty, but couldn't push it away from the attacker

Will penalties play a part?

Town stopper Danny Ward will have made note of James Henry's saved penalty against Cambridge United in the EFL Cup this midweek.

The midfielder stepped up to take the spot-kick - won by the outstanding Helder Costa on his debut at Molineux - and rolled the ball to the Will Norris' left.

The Cambridge keeper guessed correctly and stretched his big frame to keep the tamely-struck penalty out of the net.

Ward has saved the only penalty he has faced this season - against Newcastle United's number nine Dwight Gayle, who nodded home the rebound - and he will fancy himself to pull off another should the chance arise.

The Welshman had to wait five years to save the penalty against the Toon, with his previous spot-kick save coming in 2011 when he denied Slovenia's Erik Janza whilst playing for Wales U19s.

Ward faced nine penalties before he saved Gayle's at St James' Park and the 23-year-old will not want to wait that long again.

The EFL Cup trophy

How much of a distraction is the EFL Cup?

Henry could have put the midweek game to bed for Wolves had he scored his penalty, but the miss meant the Midlands club had to battle to the end to secure their place in the third round of the EFL Cup.

The Wanderers will have half an eye on tonight's draw now their spot is booked and a tie against a Premier League club on September 20 or 21 could be on offer.

Wolves have now gone six games unbeaten under Walter Zenga, with the Italian building a side to challenge for promotion to the top-tier this year.

The manager made six changes for the midweek fixture, introducing a few new names, but the core of the team remained the same.

Something that could make the difference this weekend is the fitness of the sides - with Wagner's men some of the fittest in the league and having extra days off than their Wolves counterparts'.

Substitute Jonathan Hogg scored the winner against Barnsley

Can David Wagner inspire the super-subs again?

The Huddersfield boss saw substitute Jonathan Hogg bag the winner against Barnsley last week, but super-subs have become a regular thing for the German.

Not only did Hogg and Harry Bunn combine for the winner against the Tykes after coming off the bench last weekend, but at least one substitute has scored in every league match for the Terriers so far this term.

Michael Hefele netted- in strange fashion - against Aston Villa, Jack Payne struck the winner against Newcastle and Kasey Palmer came on to sting the Bees on the opening day of the season.

Palmer's 79th minute strike against Brentford is the fourth fastest league goal Town have scored this year, showing how the Terriers have left no time for the opposition to galvanise this season.

Conor Coady in action for Huddersfield Town against Wolves

What will the return to the John Smith's Stadium hold for Conor Coady?

Conor Coady returns to the John Smith's Stadium for a second time since his departure for Molineux in 2015.

The striker has had bad luck whenb it comes to Town since leaving the West Yorkshire side, being banned for the home fixture after a red card against Brighton last year and losing 1-0 to the Terriers in the away fixture.

The last time the former Liverpool midfielder scored in this fixture was October 2014, when his 30-yard screamer saw Town beat Wolves 3-1 away from home.

The result stopped the Wanderers claiming top spot in the league and ended a nine-month unbeaten streak at home.

This time, both sides could claim first position in the Championship table with a win and Coady will be hoping for a happier return to his old stomping ground.

Town fans celebrate the win over Barnsley

Can Town stay top of the table in front of 21,000 fans?

The weekend match is set to draw a bumper crowd at the John Smith's Stadium, with the Huddersfield Examiner teaming up with the club in an attempt to beat the 20,001 attendance from last week.

The Examiner offered fans the chance to head to the match for £10 thanks to a voucher in Tuesday's edition of the paper and supporters have taken advantage.

A record crowd is expected at the John Smith's Stadium for the top-of-the-table clash, and Town could stretch their lead at the summit of the Championship table to four points, should Brighton fail to record a win against Newcastle.
