The Gunners swooped to sign the midfielder on transfer deadline day, triggering his £45m release clause, which meant they were not obliged to go into negotiations with Atletico beforehand.
The Spanish side were said to be furious that Arsenal left it so late in the transfer window to confirm their move for the 27-year-old, with reports suggesting they have refused to deal with the north London club in future.
However, Arteta has dismissed these complains, saying that there had been discussions between the two clubs before the move was made, and even if there wasn’t, a release clause always leaves them open to such a deal.
‘I don’t know,’ Arteta told a press conference on whether Atletico were left annoyed by the transfer. ‘When you have a release clause in your contract you assume that that situation can arise at any minute.
‘While the market is open it’s completely legal to do it.
‘We have had some communication with them prior to that as well so hopefully they can respect that action.’
‘Yes!’ Arteta admits when asked if he had doubts. ‘When it’s up to the last minutes it’s always a risk.
‘A lot of things have to happen at the same time. It was a challenge to do it in 24 hours but I’m really happy because at the end we managed it.’
Partey will only have his first training session with Arsenal on Thursday ahead of the huge Premier League clash with Manchester City on Saturday, but Arteta has not ruled out him playing a part in the contest.
‘Today he will have his first training session, so everything has to come really quickly for him,’ said the boss.
‘We knew that before we signed him that he is fit, he is very willing to start playing and we will see how he goes in the next few days.’
