"I was never pinning my hopes on whether an extra team got in (to the Champions League)," Lampard said in a virtual news conference. "We are sitting third, it's in our hands. This morning has just made it clear now and we have to fight for it.
"I was pretty neutral. I didn't know much about the case or any of the details. I just listened to the result this morning.
"I genuinely don't see beyond our games. We have games and we want to win them to see if we get into the Champions League. We don't worry about other teams."
Chelsea are third with 60 points ahead of Tuesday's match against relegated Norwich City but Manchester United could leapfrog the London side if they beat Southampton later on Monday.

"We are at a critical stage of the season, Norwich (City) tomorrow then Liverpool and Wolves," Lampard added. "We know our capabilities because of what we have done this season. We have to finish the job.
"Having good home form gives us confidence. With Norwich, we have to treat them with absolute respect. They can feel unfortunate with some of their results."
Lampard confirmed N'Golo Kante was still not fit but the midfielder could return for the weekend's FA Cup semi-final against United while Andreas Christensen, who came off at halftime in the 3-0 loss at Sheffield United, is fit and available.
