Google translator is poor, so I am not sure whether they are considering Martinez-Henry as a duo or as a single manager?
They are also mentioning Cocu and Oscar Martinez.
I would personally be interested in Cocu also.
He won 2 titles with Psv in 2 seasons.
Also, he was a smarter footballer than Lucho (they played together).
As a footballer he played for Barca and for a Dutch NT team as a central defender, full back, defensive midfielder, central midfielder, winger and a striker.
Maybe he understands movements, requirements and pros and cons for each position very well
Mentally he was a calm, hard working guy. Rarely losing head or getting into fights.
Played 6 seasons and 205 matches for Barca.
If Koeman is such a bad fit as majority say, and Sampaoli won't come, I would personally rather have Cocu than Valverde/Unzue/Eusebio.
