Ralf Rangnick has reportedly warned Stuttgart star Sasa Kalajdzic against joining Manchester United in the summer transfer window.
The 25-year-old forward is among the dozens of players to be linked with a move to United, who are in desperate need of attacking options.
United were forced to deploy midfielder Christian Eriksen as a false nine in the 2-1 defeat to Brighton in their Premier League opener on Sunday, although wantaway star Cristiano Ronaldo came off the bench in the second half.
Kalajdzic has caught the eye after scoring 24 goals in 58 matches since joining the Bundesliga outfit in 2019, despite the Austrian only finding the net on five occasions last season.
