Shearer was flattered to have been approached by McClaren

The ex-Newcastle striker said new boss McClaren had spoken to him about a role with the national team.

"I had already told the BBC I would extend my contract with them. I didn't want to break my word," Shearer told the Football Association's website.

McClaren added: "I fully understand the reasons behind Alan's decision. He is a top professional and a great guy."

Shearer, 35, retired from professional football at the end of last season and worked as a pundit for the BBC during the World Cup.

"I was flattered when Steve telephoned me just before the World Cup and explained the role he visualised for me, working alongside himself and Terry Venables," added Shearer.

"I met him upon my return from Germany and was impressed with his plans and his vision for the future."

But Shearer was keen to take a break from football.

As you would expect from Alan he has chosen to honour a contract to which he had verbally committed - a true mark of the man Steve McClaren

Shearer, who is currently on holiday, added: "I also want some time away from the pressures of football - I am currently on my longest ever family holiday and enjoying every minute of it."

It is a move which McClaren fully understands. The England coach said: "I would have loved to have had him on board.

"But as you would expect from Alan he has chosen to honour a contract to which he had verbally committed - a true mark of the man."

Shearer was England captain for 34 of his 63 internationals and scored 30 goals.
