World and Olympic sprint champion Justin Gatlin has reiterated his offer to Birmingham's Mark Lewis-Francis to team up with him in training in the United States.

It is an invitation Lewis-Francis could well consider following his and the rest of the British sprint team's most disappointing performance at the Commonwealth Games.

For Lewis-Francis, in particular, there was misery as he was first disqualified from the 100 metres after a false start in his semi-final.

Then in the heats for the 4x100m relay, a woeful baton exchange between Marlon Devonish and Lewis-Francis led to England crashing out.

As defending Commonwealth Games champions, and after winning gold in the 2004 Olympics in Athens, it was a title the English quartet were expected to win.

Instead, they were left redfaced and have since been subjected to severe criticism.

Yet they have an ally in Gatlin, who said: "I have good chemistry with the British guys. They are a very good group - and although I don't know any of their coaches, I think they need more discipline and guidance.

"As for Mark, I have told him to come out here and train with me. He and I are the same age and have the same goals, so why not go there together and do it?"

Gatlin believes the keys to success are "dedication and determination".

"I had support staff pushing me even when I didn't want to do it," he said.

"I know where he is coming from. Being 23 years old, your life is still young and the whole country knows who you are - so you want to party and have a good time.

"You want to live it up, and sometimes that can get out of hand. That is when you need to pull yourself aside and say 'Hey, I have a responsibility not to let my country down'.

"Personal pride for me is a big trait, because when you break it all down that's all you have."
