Bayern Munich legend Lothar Matthaus has said his former club should look to make a move for Borussia Dortmund winger Christian Pulisic. U.S. international Pulisic was Dortmund's best performer in an otherwise disappointing showing Saturday's 3-1 home defeat to Bayern, drawing specific praise from sporting director Michael Zorc, who said he was the only player to show "courage," and coach Peter Bosz. The 19-year-old is under contract until 2020, but Matthaus said Bayern should target him when they look for successors for Arjen Robben, 33, and Franck Ribery, 34. "Whenever Bayern are looking to replace Arjen Robben and Franck Ribery, they must put out feelers to Christian Pulisic," Matthaus said on Sky following Bayern's win on Saturday. The German champions have signed several key Dortmund players in recent years, with Mario Gotze, Robert Lewandowski and Mats Hummels all making the move, but Bayern CEO Karl-Heinz Rummenigge suggested in April that his club had moved away from targeting their rivals' players.
