Juventus bolstered its squad Sunday by signing Bosnian teen prospect Kerim Alajbegovic from Bayer Leverkusen on a five-year contract and bringing back French forward Randal Kolo Muani for a second stint.

The 18-year-old Alajbegovic played in all four of Bosnia and Herzegovina's matches at this summer's World Cup, after a breakout season with Red Bull Salzburg.

Leverkusen activated a buy-back clause in the deal with Salzburg before agreeing to sell the winger to Juventus for 30 million euros ($34.6 million).

Juventus also completed a permanent move for Paris Saint-Germain forward Kolo Muani, who had a successful loan spell in Turin during the second half of the 2024-25 season.

However, he struggled to make an impact at Tottenham last term, scoring just five goals in 41 appearances as the club narrowly avoided relegation from the Premier League.
