European interest in Palmeiras attacking midfielder Luis Guilherme is stepping up.

Guilherme, 17, is attracting interest from Bayern Munich and Chelsea. The Brazil U20 international has managed to play 23 competitive matches at senior level.

Transfer expert Fabrizio Romano is reporting: "Bayern and Chelsea were in attendance to follow 17 year old talent Luis Guilherme from Palmeiras vs Boca Juniors, as two of five top European clubs in the stands.

"No official bid from Chelsea and Bayern but both will keep monitoring Luis then decide about formal bid."

Manchester United are also tracking the teen.
