VMware training

This may sound a bit ignorant but I'd have to admit that I don't know much Vmware. I am wondering if VMware and Citrix must be learned together? or starting with Just Vmware VCP cert would suffice getting some background knowledge in VMware? Any advice and opinion will be very much appreciated.
Thanks

Well, what does your business use? If you use XenServer, there's no point in currently learning VMware.
