WREXHAM have caused another FA Cup upset.

The Reds, challenging for the National League title, won 4-3 against Championship outfit Coventry City at The CBS Arena.

Phil Parkinson's men were never behind in a pulsating third round tie, taking a 2-0 lead before the Sky Blues pulled a goal back.

However, Wrexham struck again to go 3-1 ahead at the break and the Reds made it 4-1 in the second half when the home side were reduced to 10 men.

Coventry, despite the numerical disadvantage, pulled two goals back and piled the pressure on in stoppage time but the equaliser never came and Wrexham held on for victory to secure their place in Sunday's fourth round draw.

Parkinson made four changes from the side that started Monday's 2-1 win at Solihull Moors.

Two were in the wing-back roles with Reece Hall-Johnson preferred to Anthony Forde on the right and Callum McFadzean replacing the injured Jacob Mendy on the left.

Max Cleworth came in at centre-back for Aaron Hayden who had picked up a knock and wasn't risked while Sam Dalby was named in attack alongside Paul Mullin, with Ollie Palmer dropping to the substitutes bench.

Wrexham made a bright start but Coventry, whose manager Mark Robins had also made changes, had the first chance in the eighth minute.

Kasey Palmer delivered a dangerous free-kick and Michael Rose stole in at the far post but the defender fired over from close range.

However, Wrexham took the lead after eight minutes.

Tom O'Connor's diagonal was brought down by Hall-Johnson for Luke Young who sent in a cross and Dalby found the back of the net with a downward header.

Coventry were almost back on level terms when Palmer's 25 yard free-kick struck the post but it got even better for Wrexham who went 2-0 up on 18 minutes.

McFadzean fed Lee and the playmaker curled his shot past Simon Moore from outside the area.

Reds' goalkeeper Mark Howard did well to parry Martyn Waghorn's low drive and the Reds' stopper managed to block Ben Sheaf's effort from outside the area.

Tom O'Connor was unable to hit the target at the other end and Coventry pulled a goal back after 36 minutes.

McFadzean was caught in possession and a cross into the area was laid off to Sheaf who fired home.

Buoyed by the goal, a Coventry counter attack led to Howard denying Waghorn but Wrexham made it 3-1 in the sixth minute of added time.

Ben Tozer's throw-in was only partially cleared, the ball was put back into the danger-zone by Young and Dalby's flick was nodded home by Tom O'Connor.

The Sky Blues had a couple of corners at the start of the second half without hurting Wrexham.

And the Reds went 4-1 up in the 58th minute when Tozer's throw-in fell to Cleworth whose shot was deliberately handled in the area by defender Jonathan Panzo.

Panzo was shown a straight red card and Paul Mullin converted the resulting penalty.

Mullin saw another effort blocked on the line by keeper Moore while Palmer struck the post for Coventry.

However, the Sky Blues pulled a goal back in the 69th minute.

McFadzean's back pass was too short and Palmer fed Viktor Gyokeres who slotted home.

Coventry made it 4-3 after 76 minutes with Palmer scoring with a free-kick from just outside the area.

There was no let-up from Coventry who went in search of an equaliser and Howard managed to tip Gyokeres shot onto the woodwork.

Todd Kane's effort was tipped over by Howard and with Coventry piling the pressure on, Palmer fired over from close range.

But Wrexham held firm to advance in the cup.
