Roberto Martinez has backed Football Association proposals to introduce a new division within the Football League that would accommodate Premier League 'B' teams.
FA chairman Greg Dyke revealed the plans on Thursday, which are ultimately aimed at increasing the amount of England-qualified players at the top-level of the game.
‘League Three’ would be made up of 10 sides from the Conference and 10 Premier League 'B' teams.
The notion, which has been suggested for introduction in 2016, has already caused much debate.
But Martinez sees the idea as a big step forward.
“I know there is going to be a lot of talk about it but I think it is very positive," said the Spaniard on Friday. “First and foremost, we need to be aware that there is a big problem in the development of our youngsters in the age group from 18 to 23. They haven’t played enough competitive football and that’s a reality.
“The Premier League have been working really hard to find a solution and now the FA have come up with something that I think is very exciting.
“I know that the 'B' sides work if they are worked at properly. I know that there are other proposals but I would be in favour of having 'B' teams because we would all get the benefits."
The Football League and Football Conference have since issued statements in response to Dyke’s plans – with neither supporting the idea.
Martinez can understand their concerns, but says the initial ideas are just a starting point from which to build.
He continued: “When you change something in football you often get a reaction which is uncomfortable and negative, which is natural. But we need to look at the problem here, which is that young English players not getting enough period of development.
“They are in a disadvantageous position with other youngsters around Europe and that needs to be solved.
“I know that there are a lot of aspects that need to be tweaked but what the FA did yesterday allows people to talk about it.”
