Diego Simeone is "grateful" for what Kieran Trippier has given to Atletico Madrid as the full-back closes in on a move to Newcastle United.
Trippier is reportedly undergoing a medical with Newcastle on Wednesday after an initial $16million fee was agreed between the clubs.
The England international joined Atleti from Tottenham in July 2019 and has made 86 appearances for the Spanish side in all competitions.
Across his two and a half seasons in LaLiga, Trippier ranks joint-fourth for assists (10) and fourth for chances created (81) among defenders.
He played a key part in Atletico's title triumph last term and Simeone has wished the 31-year-old well at his next club.
"I always look at the positives," Simeone said at a news conference on Wednesday previewing Atletico's Copa del Rey round-of-32 tie with Rayo Majadahonda.
"I'm absolutely grateful for the time Kieran has been here with us. The club gave him 48 hours to resolve the situation. He's behaved very well and been very important for us."
Trippier started Sunday's 2-0 win over Rayo Vallecano, though Marcos Llorente has also been regularly used at right-back this campaign.
However, Simeone confirmed Atletico will look to bring in a replacement for Trippier.
"We look ahead to what is next, and seek out alternatives," he said. "The club knows exactly what we need and are after.
"We are always in common agreement, but if not then we will continue with the players we have."
