Trippier, Newcastle's 34-year-old defender, knows that his side's top-three spot in the Premier League table is no guarantee of a Champions League ticket. And after Villa's impressive 4-1 win at Villa Park, he's warning his teammates that complacency is the enemy.
The Villa victory was a masterclass from Unai Emery's side, with Ollie Watkins, Ian Maatsen, a Dan Burn own goal, and Amadou Onana all finding the back of the net. Newcastle, meanwhile, were left to pick up the pieces and wonder what might have been.
Despite the loss, Newcastle remain in a strong position to qualify for the Champions League, with 59 points from 33 games. But Trippier knows that the road to Europe won't be easy, and that Villa's win was a stark reminder of the quality they'll face in the coming weeks.
"We can't use tiredness as an excuse," Trippier said. "We've been unchanged, and that's it. We focus on the next game, and that's against Ipswich."
For now, though, Newcastle's Champions League hopes are hanging by a thread. And Trippier's words of warning are a stark reminder that this season's title is far from won.
