Partey told arsenal.com: Coming here was a big change also, because I had come from somewhere where I arrived as a youth player, so there was not that expectation on me at Atletico, and not the same responsibility. When I came to Arsenal everybody saw the transfer fee, and I was coming to a club that has a lot of eyes on it.
Everybody knows about Arsenal, the profile, and I had arrived as one of the stars, there to help the team to grow. So it was a big change, and the style of play is different too. All I could do was stay positive, get used to it, and learn to deal with a new situation where everybody expects you to be at your very top level every single day. It was a good learning experience for me.
One of the reasons I joined though was for that challenge. I know the Premier League is very tough, but I wanted to feel that challenge, to test myself, and feel capable of doing it. My agent supported me a lot, and my parents, and also everybody at the club was great for me. You have to stay positive, learn from everything that happens, and just control the things that you can."
Partey added: Last year we did so well, and came very close to what we wanted to achieve.
This year we have lots of big players and I know we are capable of doing big things. It's been tough for me, being injured for a long time, but now I am ready to give everything I can to the team. Anything I can add to our level, I will do. I worked hard during my rehab to be able to come back to the level I need to be at. Now I want to get back with the team."
