Dean Richards reckons Gonzalo Tiesi will provide a major boost to Newcastle Falcons' midfield resources.
The English club snapped up the Argentina star, who has previously played under Richards at Harlequins, following an injury crisis at Kingston Park.
Back-line duo Tane Tu'ipulotu and Andy Higgins have both recently retired due to injury and several other midfield options are sidelined.
But Tiesi will be ready to take centre stage for Newcastle in time for the resumption of Amlin Challenge Cup action.
Richards' men currently sit second in Pool Three but just a point behind Brive and with a favourable double-header against Cammi Rugby Calvisano in December.
"With Tane retiring I was always looking at players just in case and we have seen injuries to other centres like Jamie Helleur, Michael Tait and Alex Crockett which have left us down to our last two or three there," said Richards.
"That has meant we could be pretty exposed if one more of those went down and we just needed to add the strength in depth that Gonzo will bring.
"Gonzo went back to Argentina to play with the national side in the Rugby Championship, and has been there since then.
"He has not really sought another club, but I have known him for a number of years and have been monitoring his progress.
"He is over here with the Argentina squad, and once that November international programme is finished he will be available for us."
