Manchester City manager Roberto Mancini has demanded twice yearly medical screenings for Premier League players after admitting he was worried not enough is being done to protect them.

The call comes in the wake of the hospitalisation of Bolton midfielder Fabrice Muamba after he collapsed on the field of play at White Hart Lane last Saturday.

Mancini cannot understand how the Premier League has allowed a situation that puts the safety of players at risk.

The Italian explained: "I was really worried on Sunday. Today I have read Fabrice Muamba has improved and I am very happy for him and his family.

"But if you want to know my opinion, it is that here in England, the best championship in the world, everything is fantastic. But we need to improve the medical side for the players.

"We need to screen the players often, maybe two times a year and they have to be more accurate because they don't do this."

"When I saw our medical two years ago, I was really worried. I said we need to do them better."
