The United boss has a strong defensive partnership with David Rozehnal and Steven Taylor, and he will not push the boat out to bring in a 31-year old.
Allardyce Set To Wait for Edmilson
Cacapa is already nearing match fitness, having completed 90 minutes against Blue Star on Monday evening, and he leaves Sam with another option.
Peter Ramage is waiting for his chance, but I have to admit, rumour from St James' Park suggests the Ashington-born defender is about to experience his last season at the club.
The one player Allardyce is prepared to wait for is Brazilian defender Edmilson, who (we believe) will be a Newcastle player in January.
Big Sam flew out to Barcelona to talk over the deal, and Newcastle will wait while he recovers from a knee injury.
