Bayern Munich coach Jurgen Klinsmann is hoping Landon Donovan will remain with the Bundesliga champions "at least until the end of the season" after agreeing to take the striker on loan from the Los Angeles Galaxy.
Donovan, who has spent the last 10 days on trial in Bavaria, should return to Munich on January 2 for a loan deal until mid-March - when the MLS season commences.
But Klinsmann revealed he is in talks with the MLS, who have already given Donovan their word that he can join Bayern, to try to make the former Bayer Leverkusen striker's stay a little longer.
"The aim is obviously to see whether we can take him on a longer-term basis," he said. "At least until the end of the season."
Klinsmann has been so impressed with the 26-year-old over the last 10 days that he may no longer need to delve into the transfer market this winter.
"This is a great situation for me," he said. "It allows me to go into the second half of the season with four strikers. He is an incredibly fast player who always looks for the one-on-one opportunities. He is a totally different kind of striker to those we already have here.
"He is now an established top player who, with over 100 international caps, has made a name for himself in North America."
He will join Luca Toni, Miroslav Klose and Lukas Podolski in the Bayern attack next year, if the latter remains with the club.
The Germany international remains unsettled due to a lack of first-team opportunities but Klinsmann is unsympathetic. "Lukas has got to come to terms with the situation and fight his way through it," he added.
Podolski has made no secret of his desire to return to his hometown club of Cologne and the club's general manager Michael Meier has said his side will be given first option on the striker as soon as Bayern decide to sell.
