The Hammers are on a roll at the moment, winning their last four games in all competitions, and going unbeaten in the last six.
This is their best run under manager David Moyes, who's also guided them to their best-ever points tally at the half-way mark in the Premier League.
The situation is quite similar in Doncaster, as the Rovers are pushing for Championship promotion and sit fourth in the League One standings.
Darren Moore's men are on a small winning-streak of their own at the moment. Doncaster have won three games on the trot, including a 2-1 win away at Blackburn Rovers in the last round of the competition.
The next assignment will be their toughest yet and it will be interesting to see which side's winning run comes to a halt.
West Ham vs Doncaster Rovers Head-To-Head
It may be a surprise to note that in 24 games between the sides, it's Doncaster who have the slightly better record. They've beaten West Ham 10 times before, although those victories came way back in the 1950s.
The Hammers aren't too far behind with eight wins in this fixture, including the most recent one coming in August 2011 when they met in the Championship.
