The Spanish giants are paying a fee of €24m to land the England global right-back from last season's Champions League finalists.
"Marca" report that it just requites Trippier to sign his contract with Atletico Madrid.
The England right-back was given a guard of honour with a difference, as the Atletico players slapped him on the back as he ran through the group.

Poldark star Aidan Turner, actress Lily James and Doctor Who's Jodie Whittaker were also spotted among the Wimbledon crowds. Meghan was also not invited to the royal box as she turned up for the event wearing jeans breaking the dress code.
While Spurs fans will be disappointed to see Trippier part company with the club, they will feel safe in the knowledge that his replacements within the squad at right-back are strong enough to justify his sale and the funds brought in.
Trippier had been one of the most impressive performers as England finished fourth at the World Cup in Russian Federation last summer, scoring early in the semi-final defeat to Croatia in Moscow, but endured a hard season last time out as his form dipped.
The defender though is set to experience football outside England for the first time in his career and will line up in La Liga with Atletico Madrid.
Atletico bid farewell to former captain Diego Godin and fellow stalwart defenders Filipe Luis and Juanfran after their contracts all expired. In January they agreed to sell France defender Lucas Hernandez to Bayern Munich for €80 million ($89.7 million).
Striker Antoine Griezmann, Atletico's top scorer in each of the last five seasons, has left for champions Barcelona for 120 million euros, with holding midfielder Rodri also departed after Manchester City paid his 70-million-euro release clause.
