Athletic Bilbao coach Ernesto Valverde admits his squad is short.
Valverde concedes he needs more players added before the LaLiga kicks off.
He said, "Now we are short of troops.
"Iigo has left and Paredes has just joined. We have several who can play in that position. Let's see, as long as the market is open there are always possibilities.
"The other day Herrera played as a central defender and today Vesga (Rayo Vallecano).
"Among all of us we have to look for solutions."
