Borussia Dortmund has successfully signed 28-year-old striker Serhou Guirassy from VfB Stuttgart on a four-year deal, valued at over $19 million, following concerns over a knee injury that will not require surgery. Guirassy, the second-highest scorer in the Bundesliga last season with 28 goals, aims to enhance Dortmund's attacking prowess. The club's managing director praised Guirassy's team-oriented play style. This signing marks Dortmund's second acquisition from Stuttgart this month, with defender Waldemar Anton also joining. Guirassy expressed excitement about joining Dortmund and his aspiration to win titles with the team.
