Di Marzio has claimed that the Gunners want the 26-year-old defensive midfielder a lot.
The Italian journalist has added that every Atletico player is for sale this summer.
Di Marzio told Sky Sports: “Arsenal want him a lot. Every Atletico Madrid player is in the market. So, it depends a lot on the offer. Atletico are open to selling every player if the offer is good.
“It also depends on budget - how much Arsenal can afford? And how much Atletico want? Atletico will want money, so it is difficult to see them doing a deal involving other players as part of it.
“They are very smart when it comes to doing deals and it will not be a surprise if Thomas Partey was to stay.
“He is young, he is not like Diego Costa, and they can sell him next year if they want or even in two years’ time. So they are in control.”
