Premier League champions have £70m offer turned down

Brazil midfielder has arrived at Newcastle training camp

Arsenal have stepped up their attempt to sign Bruno Guimarães by finally beginning formal transfer negotiations and making an opening offer, which Newcastle have rejected.

Guimarães met Newcastle’s incoming manager, Matthias Jaissle, for the first time on Monday at the team’s pre-season training camp at La Manga after a post-World Cup holiday in Brazil.

There had been suggestions that the 28-year-old midfielder would fly to London for a medical at Arsenal, but instead he boarded a commercial flight to Spain. Once at La Manga, he was expected to tell Jaissle of his determination to swap Tyneside for north London, but everything hinges on whether Arsenal are prepared to meet Newcastle’s valuation for a player with two years remaining on his contract.
