Mikel Arteta is keen to reinforce his midfield options by adding Partey to his squad this summer.
But Atletico have stood firm over the 27-year-old’s availability and will only sell him if his €50m (£43m) release clause is activated.
The report now claims that Atletico are targeting Roca but the move is dependant on whether Partey is sold this summer.
Atletico have already rejected Arsenal’s offer of Matteo Guendouzi plus £22.7m in exchange for Partey earlier this summer.
It’s also understood that Partey is keen on joining Arsenal before the end of the transfer window but he will not force a move away from Atletico.
Atletico, however, have failed to reach an agreement with Partey over a new contract as the Spanish club are keen to increase the midfielder’s release clause.
‘Honestly, I wouldn’t want him to move to Arsenal because with Atletico, he will always play Champions League football. His position is guaranteed and he will always play,’ Akonnor told Starr FM.
‘With Arsenal, I’m not too sure. Arsenal fans will kill me [for saying he should not join them].
‘I hope that, and I’m sure money issues will come in, but I hope that whatever he asks for, Atletico will be able to pay.’
