I've seen Berg play often this season and I think Berg is a very good player for Everton. AZ wants to contract him as well. He made some wonderfull goals this season and is very effective in his finishing. Berg is way better then Alves. Afonso Alves did it great in the Eredivisie, but thanks to Nilsson, the other striker of Heerenveen. Almost every goal of Alves was thanks to Nilsson.
