David Moyes believes Andy Carroll can have a major impact for England in Euro 2012.
The Everton manager is an admirer of Liverpool's No.9 and he has backed the striker to trouble opposition defences during the tournament.
"Until Wayne Rooney is available for the final group match against Ukraine, the lead role in Roy Hodgson's attack looks likely to be taken by Andy Carroll and tournament football might just suit England's latest No.9.
"In international games players can open your eyes. Carroll scored four Premier League goals last season and might seem a throwback but some big strikers who don't fit the look of an international player have ended up being key men for their countries. The one I always think of is Jan Koller.
"You had a Czech Republic team full of skilful footballers such as Pavel Nedved and Patrik Berger and then what seemed like a big diddy hanging about up front.
"Yet Koller, who was nearly 6ft 8in, turned out to be a serious player and his record for the Czechs was incredible.
"By the time he retired in 2009 he had become one of that rare group of players to score more than 50 international goals. His club career was good - he played for Borussia Dortmund, Anderlecht and Monaco - but never matched his ratio of 55 strikes in 91 appearances for the Czechs.
"In the European Championships you think of Angelos Charisteas, the great big Greek who scored the only goal in the Euro 2004 final. In that tournament he also headed a winner to knock out France.
"I've always thought Carroll has got it in him. He will be a worry to any team at set-plays and if, if England get the ball up and around the opposition box, in positions from where they can deliver crosses.
"Given you might play other teams with a Mesut Ozil or a Robin van Persie in their attacks, I don't think the French or Swedes will feel unduly nervous when they see Carroll coming short to flick the ball on and of course with flick-ons there's always an element of hopefulness: 'I hope that goes to the right person'.
"But the examples of Koller and Charisteas show you can underestimate the big man at your peril. Opponents who don't know Carroll will be more worried about him in the air and might not realise that if you give him room on his left he has a fantastic shot - it's a sledgehammer, that left foot."
