Speaking to finaria.it, the Premier League icon said: "I'm astounded they let Nketiah join Palace, because he is the type of player that scores goals, I think he is a young Ian Wright. Obviously not ready to lead the line full-time for Arsenal, but to throw him in every now and again.
"When you're beating an Everton 2-0, throw Eddie in and let him score a couple, have a couple of chances, get his confidence up. When you play against Crystal Palace at home, you win 3-0, throw Eddie in, get him a goal, get him a bit of confidence. He's a goal scorer. He comes alive in the box. That's what Arsenal need, from my perspective.
"They need a goal scorer in those vital moments to convert all the chances that they make. So, to not have anyone in their ranks that they could do that with, is astounding."
