It is not possible to say due to lack of data. However, as a first guess, an 
L network is a good candidate to provide the least match loss. You have at 
least two possible configurations of the two reactive components to choose 
from and, if you are lucky, you may have 4 possible configurations. Then you 
can choose the configuration that will have the least loss if you can model 
the Q of the inductive component and use the impedance to be matched  and 
coil Q in a tuner loss program.
