Liverpool manager Rafael Benitez and Chelsea counterpart Guus Hiddink have vowed to keep pushing Manchester United for the Premier League title.
Both won on Tuesday and are four points behind United, who had two games in hand before last night's clash with Newcastle.
Liverpool visit United on March 14 and Benitez said: 'If we win that, things may well be a lot different."
Hiddink said: "It is good for everyone in this championship to keep the pressure on the number one team."
Chelsea won 1-0 at Portsmouth and Liverpool beat Sunderland 2-0 to cling on to their title hopes.
Hiddink was delighted with the "hard-working" win.
"United are in a good position," added Benitez. "United have experience but clearly it's important for us to win. Chelsea won too so United have to win if they want to keep the difference."
Benitez, whose team faces Real Madrid in the Champions League on Tuesday, will take his side to Old Trafford on the back of a confidence-boosting win over Sunderland, which followed Saturday's defeat by Middlesbrough.
"This win has lifted everyone's spirits after the bad defeat at the weekend," said Benitez.
"We needed a win. The team needed to show character and that is what they produced."
Hiddink has enjoyed three league wins and a Champions League victory over Juventus since taking over as Blues boss and has sensed a strong desire in his players.
"What is good in this team is that they react when there are difficulties," he said. "Many players react in a way I normally don't like but this team is not happy when things are not going well and they make an extra effort to get their rewards."
