Steven Caulker spent the second half of last season on loan at Liverpool
Sunderland managed to avoid relegation from the Premier League last season, after Sam Allardyce performed the latest miracle in a long line of his famed survival missions.
Pundits and fans alike believed Allardyce's arrival on Wearside in October last year would coincide with the Black Cats becoming far more solid as a defensive unit, but the transition took rather longer than expected.
Sunderland manager Sam Allardyce has to strengthen his defensive options even further
Sunderland finished the season looking far more like an Allardyce side, conceding just nine goals in their last 10 Premier League outings. They must still look for defensive additions, however, to bolster their options with Wes Brown, John O'Shea and Younes Kaboul all on the wrong side of 30.
The acquisition of Lamine Kone proved to be an excellent piece of business for the club, but they must strive too add further quality to the defensive part of the squad.
Queens Park Rangers' defender Steven Caulker would be a terrific option for Allardyce. Standing at 6 ft 2 in, the 24-year-old has every attribute that the Black Cats boss looks for in a central defender. He is very good in the air, and strong in the tackle, whilst his marvellous physique and incredible athleticism enable him to be quicker across the ground than expected.
Steven Caulker would be the ideal signing for the Black Cats
A move would suit Caulker just as much as it would Sunderland, as he has reached a point in his career where he must find a club where he can establish himself as a regular Premier league starter, and possibly give the next England manager something to think about.
He is a fine defender, with so much potential, but one who seems to have lost his way in recent years, after being farmed from club to club.
Allardyce is exactly the man who could get the best out of Caulker, and bringing the QPR man to the Stadium of light would go a long way to making Sunderland a more cohesive defensive unit next term.
Would Allardyce consider a move for Caulker?
