New Sunderland manager Sam Allardyce has set his sights on four new signings for the January transfer window, according to a report.
Queens Park Rangers midfielder Sandro, out-of-contract striker Carlton Cole and West Ham defensive pair James Collins and Joey O'Brien are all on Allardyce's wishlist, according to The Mirror.
Sandro made his first start of the season for Chris Ramsey's side in their 2-1 defeat to Birmingham City on Saturday.
The 60-year old Black Cats manager has managed all three of the other reported targets during his tenure as West Ham United boss.
Cole is available on a free transfer, O'Brien hasn't featured since July for Slaven Bilic's side due to a calf injury, while Collins was handed his first start of the campaign in West Ham's 3-1 victory away to Crystal Palace on Saturday.
Allardyce suffered a losing start to life at Sunderland as his team went down 1-0 to West Bromwich Albion at The Hawthorns.
