West Ham have been a “much better” defensive unit since the arrival of Vladimir Coufal, according to Frank McAvennie.

The former Irons and Celtic striker, speaking exclusively to Football Insider correspondent Dylan Childs, credited David Moyes for listening to Tomas Soucek before signing the 28-year-old.

The right-back arrived in a £5.4million move from Slavia Prague on 2 October, starting all three of West Ham’s Premier League fixtures this month in the absence of the injured Ryan Fredericks.

He has made an immediate impact at the London Stadium and assisted Michail Antonio for his sublime goal in last weekend’s 1-1 draw against Manchester City.

Coufal plays alongside Hammers teammate Tomas Soucek at international level for the Czech Republic and McAvennie believes the midfielder played a big part in the deal.

“You have to give credit to David Moyes because he has listened to Soucek,” he told Football Insider.

“He has clearly told Moyes about his pal from the international setup and I am thinking, ‘Well done for going and signing him.’

“Since he has arrived they are a much better unit as a defence.

“I think a lot of it is owed to Stuart Pearce because he is clearly working with them.”

Speaking after Coufal’s arrival, Soucek said: “I think the West Ham fans will love Vladimir and he will feel connected to them.

“His style of play is very fast and intense and he will give 100% every single minute for this club.”
