"I would say the team is at least on the same level and maybe a little bit better than two seasons ago," he told BBC Five Live's Sportsweek.
"That is difficult to do so the quality we have shown is at least the same."
Cech has demanded Chelsea keep up the pressure on United by prevailing at St James Park and is confident his side have the resolve to take the title race down to the wire.
"Last week was a great week as we beat United and reached the Champions League final, which was a great achievement," he said. "We will do our best to keep our dream of winning the Premier League alive at Newcastle. If we win then the last game will be interesting.
"There is always a lot of pressure at Chelsea but we are used to this and have to make sure we keep winning games.
"You can see we have the same qualities as two years ago when we won the Premier League. We can handle the pressure and maybe win every game."
