Avram Grant has warned West Ham's rivals that the best is yet to come from in-form striker Demba Ba.
Ba completed his move to Upton Park from Hoffenheim last month after walking out on the German side, with whom he enjoyed two-and-a-half prolific seasons.
The Hammers have scored just 30 times in 27 matches this season but Grant thinks that Ba has the right attributes to make a big impact on the club's attempt to move out of the Barclays Premier League relegation zone.
"He is a very good player. I followed him for a long time in the German league," Grant said.
"He always scored, he is always moving. It is very difficult to mark him and he hits the target. That is what you want from a striker."
