Former West Ham goalkeeper Shaka Hislop feels Premier League defences underestimate Arsenal striker Eddie Nketiah.
Nketiah has impressed in the opening two Premier League wins for the Gunners and won a penalty at Crystal Palace on Monday.
Hislop told ESPN: “It comes down to misjudging the pace of the striker.
“Nketiah is quicker than many people realise.
“You need to get close to make a block, but when you do get close and make a play for the ball, it ends up going wrong.
“At the root of it is just underestimating how quick somebody is and Nketiah is quick."
