LIVERPOOL -- Jurgen Klopp has said Liverpool's activity in the January transfer window will not be determined by short-term thinking.
On Friday, Klopp was asked whether Liverpool's recent defensive improvement would alter his thinking when it came to signings.
After a difficult start to the season, Liverpool -- who failed to sign Southampton defender Virgil van Dijk in the summer -- have not conceded a goal from open play for almost a month.
"Everything we are doing has influence on ours plans," Klopp told a news conference on Wednesday. "That's all I can say about that.
"Yes it has influence, but I don't know in which way. You'll have to wait a little bit.
"I'm not sure that I get the question 100 percent. When we win a game and when we defend well then I'm happy about it.
"If we defend not that good as a team then I'm not happy about it, but I don't then think the solution is always a new player.
"I'm still a supporter because I love the game, but I cannot change my mind [clicks his fingers].
"It's really rare that I read. But for example, Alberto Moreno did fantastic this season, and then we played at Sevilla and he played not well people didn't hesitate to say: 'That's why we need a new left-back.'
"And I think: 'Wow'. But thank God, I -- or we here -- make the decisions and nobody else. We are not relaxed, but we have view on everything and it needs to fit together and everything needs to work out in the end and you need to have solutions for different situations, systems and all that stuff.
"So far it's OK, but it could have been better and it could have been much worse. Now we prepare for Arsenal and we have to be really, really strong in that game otherwise we don't have a chance."
Liverpool take on Arsenal at the Emirates on Friday, with Alex Oxlade-Chamberlain returning to the club for the first time since a £40 million summer switch to Anfield.
The England international has made a positive start to his Liverpool career, Klopp feels he needs to offer more of a goal threat.
"He did well from the first day," Klopp said. "If you are a big signing everyone expects when you are on the pitch to perform immediately. It's difficult.
"I was happy from the first day about his attitude and since he has become more and more a Liverpool player.
"I think the biggest potential he has is being involved in goal scoring situations because he has it in him -- it's unbelievable.
"But he was not asked for this too much in the past. If you watch Arsenal in the past, their two decisive players were [Alexis] Sanchez and [Mesut] Ozil. Then you are not much involved.
"Here, we put it on more shoulders. If he's on the pitch then he needs to be involved in these situations."
Liverpool defender Joel Matip has returned to training after missing the last five matches with a muscular problem but may not be fit in time for Friday's match.
And Klopp said: "Joel Matip, it's positive. I'm not sure if he's ready for Arsenal, but [he will be] for the games coming up then, I'm pretty sure. That's it, I think."
