Belying their lowly position, Wycombe came out firing with Onyedinma having the first strike in anger when his effort on the turn from outside the box flew wide.

It took Reading 18 minutes for forge their first opportunity as Ovie Ejaria played a fine pass to send Andy Rinomhota through, but Wycombe goalkeeper David Stockdale came out to make a very good block.

The hosts then had a good chance from a free-kick but Jordan Obita's effort lacked any power and was easily fielded by Rafael Cabral in the Reading goal.

Stockdale, who was making his first home start for the Chairboys, then excelled himself for a second time in the 33rd minute as he did superbly to tip a powerful, rising drive from Ejaria over the bar.

The 35-year-old's heroics kept the game goalless at half-time and his team-mates took full advantage by taking the lead four minutes into the second half.

A sliced overhead kick by Josh Knight was kept alive by Anthony Stewart's header at the back post and Onyedinma stooped to nod in from close range, with Rafael hesitant.

Reading huffed and puffed in search of an equaliser and came agonisingly close to finding one when Josh Laurent placed an effort just wide after being played in by Joao.

The Royals then had an even better chance to level after being awarded a penalty as Tafazolli, who was the last man, bundled over Rinomhota in the area and was promptly sent off.

However, Joao reprieved the now depleted hosts by sending his spot-kick against the top of the bar.

Not surprisingly, the Royals were now pressing hard and they were cursing their luck yet again when Tom Holmes' header from Michael Olise's corner was nodded off the line by David Wheeler.

Wycombe then blew a big chance to seal the points with five minutes left when Ikpeazu was bundled over in the box by Tom McIntyre, but the striker's weak penalty was comfortably saved by Rafael.

Undeterred, Gareth Ainsworth's side held on against the odds to keep their survival hopes just about alive.
