Arsenal midfielder Thomas Partey admits he hasn't been good enough this season.

The Ghanaian midfielder came in for criticism after Arsenal's 3-2 loss to Manchester United on Thursday, with the 28-year-old sloppy in possession for the Gunners' second defeat in three games.

When asked to rate his first year at Arsenal, Partey told Sky Sports: "I give myself four (out of 10) because there are moments I can really hurt the other team but there are also moments where I allow myself to lose focus and that's when everything goes down. This is when you realise that you have to get better.

"(Against Manchester United) I had a couple of moments where I gave two balls away and someone watching on TV from home or in the stadium, it is normal that they see it.

"At the end, I have to be happy with some moments, I have to learn from the bad parts and try to do better. I think they demanded more and personally I know I can give more. I have to keep working and at the end I will get the results."
