RB Leipzig wing-back Dani Olmo isn't surprised by talk of former club Barcelona watching closely Dayot Upamecano.

Upamecano has emerged as a summer transfer target for Barca.

And former La Masia prospect Olmo said: "Upamecano is very good.

"With the ball, he is very safe, I see him as a very complete central defender. In the one on one, he is very powerful, very difficult to pass.

"He is very young, only 21 years old and one of the best central defenders."
