Aston Villa defender Alex Moreno could miss the start of the next Premier League season after undergoing surgery on a hamstring injury.
The 29-year-old Spanish left-back went off injured during the 1-1 draw at Liverpool on Saturday.
"He's going to be out for two to three months. He's going to be back in early August," said Villa boss Unai Emery.
Moreno joined Villa in a £13.2m move from Real Betis in January and has played 19 times in the Premier League.
He will miss the home match with Brighton on Sunday, where a Villa victory would take them into the Europa Conference League and secure European football for the first time since 2010.
