Brighton have agreed a deal for Germany midfielder Mahmoud Dahoud to join on a free transfer when his contract with Borussia Dortmund ends on 1 July.
The 27-year-old is a Syrian-born defensive midfielder and will join on a four-year contract.
The Seagulls have also signed Brazil forward Joao Pedro from Watford and Liverpool midfielder James Milner.
“I’m sure he is going to be a top player for us,” said Brighton boss Roberto de Zerbi.
“I’m excited to have Mahmoud in my team. I wanted him when I was at Sassuolo.”
Dahoud has been capped twice by Germany and played 141 times for this season’s Bundesliga runners-up, but was restricted to just 10 appearances after having shoulder surgery last summer.
The deep-lying playmaker broke through in the 2015-16 season, helping Borussia Monchengladbach qualify for the Champions League, and was signed by then Dortmund manager Thomas Tuchel in 2017.
Along with Milner, Dahoud adds much-needed European experience to the Brighton midfield as they prepare for a first campaign in the Europa League following their sixth-placed finish in the Premier League.
Dahoud will also help make up for the loss of Argentina’s World Cup winner Alexis Mac Allister to Liverpool.
Brighton technical director David Weir said: “His [Dahoud’s] quality and ability will really add to the options available to Roberto.”
