Fulham failed to move 10 points clear of the relegation-threatened Toffees in the table, adding to the woes of last week’s Carabao Cup and FA Cup exits.
“With the result, I am disappointed,” Silva said. “Both teams had chances to score and it was clear we were the most dominant on the pitch.
“We created many chances to score, we had good moments but we missed putting the ball in the net.
“It is not a good thing (Fulham missing chances). The decision making has to be better in the final third of the attack. We need to be more assertive, more calm in some decisions because we arrived in so many dangerous areas.
“We need to be more ruthless and clinical in moments.”
Jimenez netted four goals in December but looked a shadow of himself against Everton.
“To be honest with you, I am not expecting many things towards the end of the market,” Silva added. “If it was possible to do something we should of done it at the beginning of the window because we had a semi-final to play and the FA Cup.
“The board are trying to do their best but if you ask me if we are going to do many things at the end of the market, then no.
“I will not talk about players that are not our players and rumours.”
Everton manager Sean Dyche talked up the England number one.
He said: “I thought he had a good performance. He is England’s number one and we have a high expectation of him.
“His decision making was good tonight and as a team we worked very hard in front of him, we had a collective mentality. He played his part tonight without a shadow of a doubt.”
