West Ham United's start to the season has seen them pick up 18 points from the first 11 games, claiming five wins already, including victories over last season's top two, Liverpool and Manchester City.
Manager Sam Allardyce has rightly earned plaudits for revolutionising the way West Ham play, switching to a 4-3-1-2 system and getting the best out of new signings Aaron Cresswell, Alex Song, Diafra Sakho and Enner Valencia.
Whilst it's all been incredibly positive for the Hammers so far this season, there is one lingering problem - the future of star centre back Winston Reid.
The New Zealand international, 26, has been superb for West Ham for some time now, but that has led to heavy interest from the likes of Arsenal, Liverpool and Manchester United.
West Ham's position is weakened by the fact that Reid's contract is set to expire next summer, and clubs seem to be queuing up to take him away from Upton Park.
With no deal agreed, West Ham need to start looking for possible replacements for Reid, and whilst speculation has linked them with a move for Fulham's Dan Burn, there's another name on their radar.
According to the Daily Mail, West Ham sent scouts to watch Austrian international centre back Aleksandar Dragovic this weekend, as he took on Russia for his country.
Dragovic, 23, was heavily linked with a move to Arsenal in 2013, but chose to move to Ukraine with Dynamo Kiev instead, and his impressive displays there have led to speculation over a move to Juventus.
However, West Ham clearly have high ambitions, and landing Dragovic would be some coup for Allardyce, and have even been linked with Dragovic's international centre back partner.
Red Bull Salzburg star Martin Hinteregger was also scouted by West Ham, and it's becoming more and more apparent that the Hammers are concerned over Reid's future.
Centre backs are being linked with moves to Upton Park on a regular basis now, and fans may have to start accepting that Reid could be on his way out of the club - but it seems that Allardyce and West Ham are already making plans in case he does leave.
