Leeds are hoping to complete a deal to sign Hamburg striker Pierre-Michel Lasogga on a season-long loan, Press Association Sport understands.
The two clubs are in advanced talks over a loan move with a view to a permanent deal and Leeds are confident of reaching an agreement over Lasogga's wages before Thursday's transfer deadline.
Lasogga, who was reported to have travelled to England on Monday, has been Leeds' top transfer target all summer and is keen to join their promotion push under head coach Thomas Christiansen.
Leeds sold last season's leading goalscorer Chris Wood to Burnley for B£15million last week, but have refused to break their current wage structure to land Lasogga.
The 25-year-old, who has not appeared for Hamburg this season, scored eight goals in 30 Bundesliga appearances in the last campaign.
Leeds were intent on adding new strikers to their squad before Wood's departure, but have stepped up their search following injury to summer signing Caleb Ekuban.
Ekuban sustained a foot injury in the recent win at Sunderland, while Leeds paid an undisclosed fee to Dutch side NEC Nijmegen last week for teenage striker Jay-Roy Grot.
Christiansen remains unbeaten at Elland Road since replacing Garry Monk in June and saw his side climb to third in the table at the weekend after victory at Nottingham Forest.
