In an exclusive interview with Football FanCast, Steve Bull, who made 561 appearances for Wolves, believes they can't play with a back four and that everyone knows using a back three is the way forward for them.

Nuno Espirito Santo was rocked with the double defensive blow before their game against West Ham, as Jonny has suffered a double cruciate ligament injury and Willy Boly tested positive for Covid-19, forcing them into a back four.

Since Nuno took the job Wolves have mainly operated with a back three consisting of Conor Coady, Romain Saiss and Boly as their central defenders, but they appeared lost without Boly during their defeat to the Hammers.

Speaking on why a back four doesn't work and why a back three is the way forward while they have a lack of defensive cover, Bull told FFC:

"We tried to play with a back four halfway through the season and we lost quite a few in games, so that tells me that it just doesn't seem to work.

"I think everyone at Wolves realises that a back three is the way forward for the club with our wing backs flying forward."

Wolves lost a key player to their system last summer in Matt Doherty and Nelson Semedo has not been able to fill the void left by the Republic of Ireland international.

Nuno has had to cope with a number of injuries this season across his whole team including two of his players getting knocked out in Raul Jimenez and Rui Patricio.
