Manchester City chief Patrick Vieira says their new training complex will be the best in the world.

Construction of the £100million City Football Academy on waste land next to the Etihad will begin in the next few days.

The site is the equivalent to five Etihads and includes:

- A 7,000-capacity stadium for youth and reserve games.

- 16 full-size pitches, including one indoors.

- A 400-player Academy with classrooms for 200 pupils.

- On-site accommodation for junior and senior players.

- A state-of-the-art first-team building complete with injury and rehab centre.

- A bridge linking the Etihad to the site.

The project has been four years in the planning and involved extensive research into 30 top sporting complexes around the world.

Vieira said: "What I find really exciting about the project is that before designing the facilities, they have been to the football world, the basketball world and the NFL world.

"I believe it is the best project in all of sport because people have travelled the world to capture the best in every sport and bring it here.

"It is a long-term commitment and I am really excited about it because once you see the pictures you can't wait for the work to start."
