Mikel Arteta has remained tight-lipped about the prospect of further additions to Arsenal’s squad before the transfer window closes, despite the club retaining an interest in Eberechi Eze. The Gunners have already made six signings this summer - including Viktor Gyokeres and Cristhian Mosquera - with their total outlay in the region of £200million. They are still interested in Crystal Palace playmaker Eze, who has a release clause worth over £60m in his contract. Earlier this summer, Arteta admitted that he felt the squad was “short”, but that was before the arrivals of Mosquera and Gyokeres. And asked on Tuesday if he still feels that way and what more could be needed in terms of additions, Arteta replied: “I said that I was extremely happy with the way that we have approached the window and how aggressive we’ve been. “There’s still a long period with the window open. So far, we are very happy with what we have achieved. Make sure that at the end of the window, we continue to be super happy.” Arsenal have one match remaining on their pre-season tour of Asia, with a north London derby against Tottenham set to take place in Hong Kong on Thursday. It will be the first-ever north London derby played abroad, and Arteta believes it is a positive move. “A great idea,” he said. “I think to bring football tradition, a rivalry, but at the same time to do it in a completely different country, I think it’s brilliant. “I think it’s an opportunity for everybody to feel that and for us as well, because for our preparation, increases the competition level again and it brings a different challenge to the game. “And then we’re going to be so lucky to play in this incredible stadium with 50,000 people that I’m sure they’re going to be super loud and passionate.”
