Former Liverpool defender Mark Lawrenson has revealed that Arsenal have big problems to deal with ahead of their London derby against West Ham United this weekend.

The Gunners will travel to London Stadium on Saturday afternoon as they look to catch up fourth-placed Chelsea in the Premier League table.

The Hammers have made a solid start to the season but they can now challenge their London rivals in their way to top four finish.

Meanwhile, former Liverpool star turned to BBC pundit Lawrenson admits Unai Emery side are able to win this weekend’s game, but still, have a big problem at the back.

“Normal service will be resumed this weekend in terms of Premier League teams going with their strongest line-ups after resting players last week – not just here, but across the division,” Lawrenson said.

“Both of these sides are safely into the next round of the FA Cup after beating lower league sides – I was at Blackpool to see Arsenal cruise through.”

“In the Premier League, the Hammers’ form has been very up and down in recent weeks. But the same could be said about the Gunners.”

“I am going for an Arsenal win here, but it is clear that Unai Emery still has a lot of work to do.”

“He has only been in charge for half a season and I think that, when they come up against the top teams, the same problems still remain.”

“The main issue is at the back. Would I back them defensively? No, absolutely not.”

“Too many of their defenders are not Champions League level, which is the standard they need them to be at.”

During his press conference ahead of the game, Arsenal boss Emery said: “I think West Ham are improving and they also have good individual players with quality, like Anderson, like Arnautovic, who are very good players.”

“Usually [Manuel Pellegrini has] very offensive teams. They usually play matches with a balance tactically but above all with technical, offensive players.”
