With West Ham defeating Leicester City 2-0 at Upton Park today, the Hammers continue to push towards a top four place, though January additions will be required in order to continue their great form.
Adding a central midfielder will be needed with Alex Song and Cheikhou Kouyate in line to play at the African Cup of Nations in 2015, but centre back continues to be an area of concern.
Star defender Winston Reid is out of contract next summer, leading a number of top sides to consider a move to sign the New Zealand international in January.
West Ham have subsequently been linked with a host of different centre backs, including Aleksandar Dragovic, Dan Burn, Martin Hinteregger and Nicolas Nkoulou - but their top target could be far less illustrious.
Canadian international Doneil Henry spent time training with West Ham earlier this season, and now Sam Allardyce is on the verge of making the 21-year-old his first January signing.
The 14-cap international is an athletic defender who has a great turn of pace, and has mostly represented Toronto FC as a professional, even though they recently sold his rights to Cypriot side Apollon Limassol.
A work permit application for Henry has been submitted by West Ham, and they hope to announce his arrival on Monday, according to the Daily Mail.
A £1.5m deal is on the verge of completion if Henry is handed a work permit, and could be seen as the long-term heir to Reid if the 26-year-old departs in the coming months.
