The agreement includes an obligation that could make the transfer permanent next summer if specific performance related conditions are met. While neither club has revealed the exact details of the clause, it is understood that factors such as the number of appearances Garnacho makes next season are expected to activate the deal. Chelsea are confident those requirements will be fulfilled, allowing them to receive a fee close to their original £43 million valuation.
The 22-year-old has already agreed a four year contract with Villa, paving the way for a long term stay if the conditions are satisfied.
Garnacho's move comes shortly after Chelsea completed the signing of Morgan Rogers from Aston Villa in a club record £117 million transfer. The arrival of Rogers, along with Sporting winger Geovany Quenda, increased competition for attacking places at Stamford Bridge and made Garnacho's departure more likely.
Villa manager Unai Emery welcomed the signing and praised the winger's quality and commitment.
"He is so talented, young and he showed us his wish to help our project. We are really happy," Emery said.
Garnacho becomes Villa's fourth signing of the summer following the arrivals of Johan Manzambi, Joao Gomes and Modou Keba Cisse. The Midlands club have also balanced their spending by generating close to £200 million through player sales, including the departures of Rogers, Youri Tielemans, Donyell Malen, Enzo Barrenechea and Lewis Dobbin.
Chelsea signed Garnacho from Manchester United for £40 million last September, but he struggled to establish himself during his only season at Stamford Bridge. He managed one Premier League goal and finished the campaign with eight goals and four assists in 43 appearances across all competitions. Manchester United are also expected to receive 10 percent of any future transfer fee under the terms of his original move.
At Villa, Garnacho will be aiming to revive his career under Emery, who has earned a reputation for developing talented players. The winger had also attracted interest from Roma, but Villa's loan structure offered financial flexibility while complying with Premier League and UEFA financial regulations. If he improves on his previous output and meets expectations, the move is expected to become permanent next summer.
