Pierre-Michel Lasogga might be lethal for Leeds United this season, but they should be wary about a permanent deal.
Leeds United wrapped up a deadline-day loan deal to sign Hamburg striker Pierre-Michel Lasogga.
The 25-year-old is one of two strikers to arrive at Leeds - along with 19-year-old Jay-Roy Grot - since 30-goal marksman Chris Wood left for Burnley last month.
And history suggests Lasogga could do the business for United in the goalscoring stakes this season, but long-term he might go off the boil.
Lasogga was signed by the Bundesliga side in 2014 on the back of excellent loan deal from Hertha Berlin, scoring 13 league goals in 18 starts - one less than Marco Reus and Roberto Firmino - but only 13 top-flight goals have followed since then.
His first season at Hertha was similarly impressive as Lasogga struck 13 goals in 19 starts for Hertha in the second tier of German football during the 2010-11 season.
With that in mind, it might suggest that the German - who would've earned a Germany cap only for an injury which made him withdraw from Joachim Low's squad in 2014 - is lethal in his first season at a club, when he has something to prove, but his form then nosedives.
At Hertha and Hamburg, his goal tally decreased every year despite an excellent first season at both clubs, and that is something for the Leeds hierarchy to consider if he scores enough goals for the Whites to potentially earn a permanent contract.
