Chicago Fire trialing four players including Jeremiah White
Heading that list is former AGF Aarhus and Al-Ettifaq winger Jeremiah White who could be added as the Fire are searching for a player with speed.
Technical director Frank Klopas says that the club is keen to bring in new players but admits that it is tough because some of their targets are still under contract.
''We're always looking, but a lot are under contract already,'' he said.
''One thing we learned is that we need to be focused for 90 minutes. Maybe we need one more player, one with more speed. ... But they're hard to find.''
The Fire are also taking a look at AS Monaco midfielder Malaury Martin, Serbian Bratislav Ristic and 20-year old Mexican Victor Perrales.
