Transfer round-up: Brighton land Dahoud, Smalling stays with Roma

Brighton have announced the signing of German midfielder Mahmoud Dahoud from Borussia Dortmund.

The 27-year-old will join Albion on a four-year contract on July 1 following the expiry of his deal with the Bundesliga club.

Syria-born Dahoud, who was capped twice by Germany in 2020, becomes the Premier League side's third signing of the summer following deals for Joao Pedro and James Milner.

Seagulls head coach Roberto De Zerbi told his club's website: "I'm excited to have Mahmoud in my team. "I wanted him when I was at Sassuolo and I'm sure he is going to be a top player for us."

Dahoud began his career with Borussia Monchengladbach before moving to Dortmund in 2017.

He went on to make 141 appearances for this season's Bundesliga runners-up, although his game time was restricted after he had surgery on his shoulder last summer.

Brighton technical director David Weir said: "We're delighted to bring Mahmoud to the club, his quality and ability will really add to the options available to Roberto.

Manuel Lanzini will leave West Ham when his contract expires at the end of June.

The Argentinian midfielder joined the Hammers from United Arab Emirates side Al Jazira in the summer of 2015 and has made 226 appearances, scoring 32 goals.

Lanzini's most memorable moment was his long-range equaliser at Tottenham in 2020 as West Ham came from 3-0 down to snatch a 3-3 draw.

The 30-year-old has been linked with a return to Argentina and former club River Plate.

Manager David Moyes told the club website: "Manu is a fantastic professional, a really good lad, and whichever club he joins will have an excellent player on their hands.

"We are sorry to see him go, but he deserves the opportunity to play more regularly elsewhere, and we wish him well in his
