The 22-year-old striker has joined the Yorkshire club on loan from German club RB Leipzig for the rest of the season.
Leeds will have an option to sign him permanently at the end of the season if they secure promotion to the Premier League.
Former Leeds player Andy Couzens has taken to social networking site Twitter to express his reaction after the club confirmed the deal today.
Great signing for us looking forward to see him play a bit tomorrow night. #mot https://t.co/JZCaIn30QU

Leeds badly needed a striker this month following the departure of Eddie Nketiah who returned to Arsenal after his loan deal was terminated.
