Burnley boss Sean Dyche says any new signing must be able to fit into the club's culture.
The Clarets have made one new addition so far this month, bringing in Georges-Kevin Nkoudou on loan from Tottenham.
But Dyche said any new additions would have to work within the model of the club and be able to affect the team.
"Only if they fit the model that we work to," Dyche said when asked about incomings this month.
"Only if they can affect the team, which is obviously the key principle, they have to fit in the numbers, the way the club is run, so that is the key – we are in a good situation as a club so we have too continue that and choose wisely.
"That is why when you see some of them players we are linked with, it is always interesting I never know how it goes beyond the fact that some are on 100k a week, we aren't there, trust me."
Steven Defour, meanwhile, insists confidence hasn't been shaken by their recent run of poor results.
Defour insists confidence remains high.
“We have the feeling that we should have got something from this game, but we didn't," he said.
“We know we played a good game so we'll just have to continue to work hard.
“The margins are very tight. We're playing good games, we're not playing really bad. Maybe just the first half at Crystal Palace wasn't as good. We're still in a good position so we'll just have to continue to work like we do and at some point we'll win.
“We've played again with confidence, we've just gone up against Manchester United. They're a strong team and second in the league.
“We were unfortunate. I think we played a good game. I don't think United had too many golden opportunities when hitting us on the counter attack. We had some chances in the second half to score a goal."
