Newcastle have signed French winger Allan Saint-Maximin from Nice for a reported 16.5m.
Saint-Maximin, a France Under-21 international, has signed a six-year deal at St James' Park.
"He has all the attributes you would want in an attacking player," manager Steve Bruce said.
Earlier on Friday Newcastle announced the signing of Netherlands defender Jetro Willems on a season-long loan from Eintracht Frankfurt.
The 25-year-old left-back - who has 22 international caps - made 36 appearances for the Bundesliga outfit last term.
Bruce said: "I'm delighted to bring Allan to St. James' Park. He is a very talented young player with a big future ahead of him.
"He has all the attributes you would want in an attacking player, including lightning pace, so I'm sure he'll excite everybody. He is a great addition to Newcastle United and the Premier League."
