Watford boss Silva remains confident that there will be some movement in the remaining 13 days, though he concedes that certain Premier League clubs have more money to throw around than others.
"We as a club are working to do what we can do during this month and in the market as well," he told reporters ahead of Saturday's trip to Leicester. "Day by day I speak with [technical director] Filippo Giraldi, sometimes with our owner as well.
"We are doing what we can do in the market. Of course, you know, it's not an easy market. Some clubs have big power in the market to do - the others, not so well.
"It's important to understand our situation and try to do our best to improve. I understand the market is still open - it's open until the 31st - but what is most important for me after my job is to keep focusing on the players I have ready to work and to prepare for the games as well.
"I don't like to stay every time here to talk about the new players. My job is to work with the players we have. I try to do my best to develop them and to improve our team as well. Of course behind that, day by day with my players I need to do my job as well."
