The forward has penned a four-year deal at Elland Road, reportedly costing the Premier League newcomers around £30 million ($40 million).
The 29-year-old said he was excited to join the club and was looking forward to working with Marcelo Bielsa, whom he described as one of the best coaches in football.
“It’s a new step in my career and I want to help the team to achieve the goals of the season,” he told the club’s Twitter account.
Leeds have been working for two weeks on this deal with Valencia — we knew Valencia have some problems now as we didn’t achieve the Champions League.
“Since the first time Victor (Orta, director of football) talked to me I knew I wanted this new challenge with Leeds.”
Rodrigo, who can operate as a winger or striker, spent time at Celta Vigo and Real Madrid as a young player before moving to Benfica.
