Eder Sarabia will follow Quique Setien to Barcelona.
Sarabia is to be named Setien's No2, having worked as assistant coach to the 61 year-old at Las Palmas and Betis. Setien played with Sarabia's father, Manu, at Logrones.
While Setien is known to be quite laid back on matchday, Sarabia is infamous for his intensity on the touchline. Indeed, he was accused by Valencia fullback Jose Luis Gaya of trying to unsettle him during last season's Copa del Rey semifinal.
"He spent the whole game shouting at me, telling me to stop diving and trying to shake my concentration," said Gaya. "It is not the first time he does it. In Seville and last year he did the same."
