BRUSSELS, Oct 14 (Reuters) - Spain's Telefonica (TEF.MC) hopes to complete the acquisition of Brazil-based GVT (GVTT3.SA) in about two months if no counterbid emerges, the company's chairman said on Wednesday.

"I really don't know (whether there will be a counterbid). GVT is very complementary for Telefonica ... (If there isnt any bid) the deal could be closed in something like two months," Cesar Alierta said in an interview with Reuters Television.

Telefonica's Brazil unit Telesp made a 6.5 billion reais

($3.78 billion) offer for GVT last week, topping a previous bid by Vivendi (VIV.PA) by 20 percent.

With regard to Telefonica's interest in buying Telecom Italia's TLIT.MC's German broadband unit Hansenet, Alierta said talks are advancing and the final outcome should be seen before year-end.

"I think we are getting closer, but we will see in the coming weeks. I think whatever happens will happen before year-end," he said.

TAX ADVANTAGES

On the matter of the conflict between Spain and the European Commission over alleged tax advantages for companies investing abroad, Alierta said he expects a satisfactory solution for all parties, including Telefonica.

The alleged advantage for the companies lies in the possibility of their being able to deduct part of the goodwill generated by overseas acquisitions.

Telefonica booked goodwill of 9.3 billion euros ($13.86 billion) with the buy of UK telco O2, which according to Spanish law can be deducted from future tax payments, providing about 2.8 billion euros in deductions, BPI analysts said in a research note.
