Borussia Dortmund striker Sebastien Haller on Tuesday vowed to ‘come back stronger’ as he thanked fans for their support following his diagnosis for a testicular tumour.
Ivory Coast’s Haller joined the German club earlier this month as a replacement for Erling Haaland, who has signed for Manchester City.
But the 28-year-old left the team’s pre-season training camp in Switzerland on Monday after a tumour was found in his testicle.
