Former Ivory Coast international Kolo Toure believes compatriot Eric Bailly could develop into one of the best defenders in the world at Manchester United.

The 22-year-old has impressed at Old Trafford since joining United from Villarreal ahead of the 2016-17 campaign and Toure has little doubt he will continue to get better under the tutelage of Jose Mourinho.

"He can be a big, big player for United. He can be the future for United," Toure told United Review.

"What he's doing right now is amazing and I think his future is really, really bright. He will improve and if he learns from Mourinho then he can become one of the best defenders in the world. He's tall, technically very good, has brilliant vision and he's really calm. That calmness is the most powerful attribute he's got.

"He can be up there with the top defenders United have had. He's young and will learn from working with one of the best managers in the world, and of course he's going to get better. Definitely.  

"He's here to play football and he's really enjoying his time in Manchester with his family. You can tell that just from the way he's playing. He's enjoying the city and he's a really good boy."
