Tottenham boss Mauricio Pochettino admits the January transfer window is not the easiest but is open minded about bringing in new signings.
When asked about possible moves for Lucas Moura or Malcom, the Argentine said: "No news. There are a lot of rumours, different names.
"This transfer window is difficult because it's only three-and-a-half months left of competition. It's so difficult to add players now; quality players who can help us to try to win games and achieve all we want.
"If you want players who arrive to the Premier League, you need to know and to be sure if you are going to invest big money.
"All the players need time to adapt for themselves, in a new league or when you change the club and you play in a different philosophy.
"Sometimes you believe it's going to help, and sometimes you are going to create a problem - that is why the transfer window now is so difficult.
"We are always open and I'm so open to adding some players."
