The striker has scored three times in two games and looks to have settled in quickly at Upton Park, despite that spat with Alan Curbishley after one poor Hammers performance.
Toshack wants to see Bellamy give the Germans something to think about in their Euro 2008 qualifier in Cardiff on Saturday.
Wales will be massive underdogs against the unbeaten Group D leaders at the Millennium Stadium, before they head off to face Slovakia in Bratislava the following Wednesday. And Toshack knows he needs big performances from his experienced Premier League players.
Toshack: "I am delighted to see how well Craig has done at West Ham. After the start he has had he will probably be ready to take on the world now.
"I have also noted West Ham manager Alan Curbishley's comments about Craig and the way he has hit form already this season.
"That is good to hear and I just hope he can continue in that vein for us in the next two internationals."
Curbishley admits he initially underestimated the talents of Craig Bellamy - a player he now believes can become an Upton Park legend.
