He wrote for the Sunday Times: "I rate Higuain so highly that I believe he'd have similar scoring numbers to Sergio Aguero if he'd been at Manchester City for the past eight seasons, as his compatriot has.
"With their mix of grit, determination and Latin flair, Argentinians are among the best players out there. They're happy to go to war for you and won't be rolled over.
"Higuain's similar to Aguero but not quite as sharp over the first few yards, that ridiculous explosive speed Aguero has. As Argentina's manager, you would probably pick Aguero of the two because he's six months younger and slightly sharper in tight areas.
"Yet, in assessing where the ball might drop in the box and the movements they make, they're on a par. Like Aguero, Higuain's a lovely finisher, whether it's spectacular volleys or simple tap-ins. All top strikers are craftsmen and clean kickers of the ball.
"Although I fancy City to win today, Chelsea now have a striker capable of nicking a game for them away from home at a difficult venue. Higuain can dig them out of a big hole in a way I didn't see either Giroud or Morata doing as their centre-forward, so it's not impossible they will find a way to win."
