Mikel Arteta knows how he wants to improve Arsenal's squad this month but warned the transfer market is "very complicated" in the current climate.

Julian Brandt is among the reported targets for the Gunners during the January window, although Borussia Dortmund sporting director Michael Zorc insisted there had been "no offers at all" for the midfielder.

Arsenal boss Arteta this week revealed Mesut Ozil could be on the move after DC United and Fenerbahce were linked with the out-of-favour playmaker.

The London club allowed Sead Kolasinac to return to Schalke, but there has been very little transfer activity just over a week since the window opened.

Arteta would like to do get his business done early in the window, but in a week that saw Arsenal take a short-term £120million Bank of England loan due to the impact of the coronavirus crisis, the Spaniard is being realistic with his expectations.

Asked about the prospect of making early signings, he said ahead of the FA Cup third round tie with Newcastle United on Saturday: "I don't know. At the moment the market is really complicated and the situation around every club is not easy.

"To get the negotiations going it's not easy, it makes it harder because you can't be face-to-face and you cannot travel to another country to make that happen, it has to be on the phone or Zoom.

"It can go either way. I can tell you what I would like, with the players out and in sorted, but I think it's really complicated."

Arteta says it is important to understand that players may want to move on due to the pandemic.

He added: "It's affecting everything. It's affecting things transfers financially, it's also affecting some players who are here and they are stuck here for a year and realise 'I need to go back home, I need my family to be happy, to be next to me'.

"It's a bit of a mixture, but players are experiencing different feelings that probably are new to them and that's why I keep insisting this virus is about mental health as well as how you are feeling physically. Mental health is a big, big thing that we have to pay more attention to."

One player who has arrived at Arsenal is 19-year-old defender Omar Rekik, who joins the under-23 squad from Hertha Berlin.
