Matip trained on Tuesday with Liverpool during their warm weather break in Barcelona after missing Sunday's calamitous defeat to Bournemouth with an ankle injury.
The Cameroon centre-half has been hugely impressive for Liverpool and the Reds' only two defeats this season have come when he has been crocked.
Liverpool have conceded nine goals in the 11 Premier League games he has played, which is the same total they have leaked in the three matches without him.
Matip, 25, trained with his teammates this morning at the Centre Alt Rendiment in Saint Cugat.
He did extra work with fitness coach Andreas Kornmayer to sharpen his fitness following his lay-off.
