Middlesbrough chasing £6.5m striker Alves

The 26-year-old scored 34 goals for Heerenveen in Holland last season.

Alves said: “Middlesbrough are seriously interested. They have made this clear by bidding millions of pounds for me.

“I’d always be open to joining such a big club as them and to playing in the Premier League.

“The initial contacts and discussions with them certainly seem very promising.”
