Exclusive – Grobbelaar expects Arsenal against Liverpool to be decided by defensive error

Bruce Grobbelaar has told talkSPORT that he believes Liverpool's FA Cup clash with Arsenal will be settled by a defensive mistake.

The Reds blew the Gunners away 5-1 last weekend at Anfield and grabbed a stunning four goals in the opening 20 minutes.

The Liverpool legend claimed the lightning start was the best beginning he had ever witnessed but said he expects a far more cagey affair this Sunday, live on talkSPORT.

"They [Arsenal] are going to come out like a house on fire which might play into the hands of Liverpool because Liverpool on the counter-attack these days are fantastic," he told Kick Off.

"But this game is going to be totally different. It’s either going to be a very high scoring game or it’s going to be one of those games where it’s cat and mouse like a chess game.

"I envisage it’s going to be like that [cat and mouse] and just the odd mistake in defence is going to be the key."
