Arsenal signs Spain midfielder Zubimendi from Real Sociedad

Arsenal has completed the signing of Spain international midfielder Martin Zubimendi on a "long-term" contract. The 26-year-old, who had spent all of his career with Real Sociedad, joined last season's Premier League runner-up for 51 million pounds and becomes the second player from the San Sebastian outfit to join Arsenal, after the arrival of Mikel Merino last summer.

Arsenal coach Mikel Arteta welcomed the signing of one of his club's key summer targets. Arsenal is also thought to be closing in on a deal to sign Noni Madueke from Chelsea, with the England winger said to have agreed to a five-year contract at the Emirates.
