On 20 June 2017, the Administration of Panathinaikos rejected the first offer of Al Ain FC (€2.5–3 million) about the purchase of experienced Swedish striker. The Greens are holding the 55% of the rights of 31-year-old international (his former team, Hamburger SV, have the other 35%), whose current contract expires in the summer of 2019, with a buy-out clause of €5.2 million, but the negotiations with the UAE club are expected to be continued, while Berg has already agreed to sign a two (plus one) years' season contract with Al Ain, with an annual salary of €3 million after taxes.
