Dini talked about Zubimendi in an interview a few days ago, and he expressed his views.
Dini said: "I think he can improve Arsenal's ball control ability, but his physical fitness and defensive awareness are somewhat lacking," said Dini.
"As far as I know from Liverpool insiders, they are not too disappointed that they were unable to sign Zubimendi. They think Zubimendi will make the team's game slower, so it will be very interesting to see how Arteta integrates Zubimendi into the team."
