Arsenal are now finalising a record deal for the Argentine.
Gibson, who now works as a Spanish football expert, told talkSPORT: “Arsenal are getting a very good player. I’m amazed Real Madrid are considering selling him.
“He’s 25 years old, so he’s only going to get better. He’s been a great player for Real Madrid. Sometimes clubs and supporters get bored with the same strikers. I don’t see any reason why Higuain would leave. If Arsenal could get him for under £20million then that’s a steal.
“There’s no guarantee with a new player that he’s going to settle and fit in with the team. Higuain is settled and proven [at the Bernabeu].
“He’s perfectly suited for the Premier League. He’s got a good physique, is a really tidy all-round footballer and a great finisher. He’ll settle in the Premier League well with his style of play. He’s not a Lionel Messi or a Cristiano Ronaldo, he’s more of a Radamel Falcao, just an out-and-out number nine.
“He’s what Arsenal need. They have a lot of players who can keep and move the ball but they need a focal point up front and he can provide that.”
