The £ 20m move by Kieran Trippier from Tottenham at the Athletic Madrid is undoubtedly one of the leftmost moves of this summer's transfer window.
The 28-year-old British national has put a three-year contract for Diego Simeone's team on paper and it is fair to say that it was a bit of fun among some sections of Liverpool support.
Trippier's last game for Tottenham as we have seen was the final defeat of the Champions League last month against Liverpool in Madrid, a game obviously played at the Wanda Metropoliano stadium, the home of .. his new Atletico club Madrid.
Some Liverpool supporters have calculated the meaning and accepted Twitter to express their opinions.

Trippier joined Spurs at Burnley in 2015 after Tottenham reached his 3.5 million pound share after Burnley's relegation to the league, but it is clear that the Clarets do not have a sell-on clause on the deal that brought him to White Hart Lane.
The right-back made 185 appearances for the Clarets after joining Manchester City, initially on loan, at the start of the 2011/12 season.

He was named in the Team of the Year of the PFA Championships in 2012-13 and 2013-14, while he also won the prize for the player of Burnley's year in his first season at the Turf Moor.
The 28-year-old spent four seasons at the Spurs, making 114 appearances for the team in all competitions, scoring two goals and providing 24 assists.
There has been much speculation about the defender's future, with a number of clubs wishing to sign him this summer.
Naples and Juventus were the first teams to make a move, but it is the Spanish giants who won the race for his signature.
