Hi everybody,
“Pleased to meet you. We’ve heard so much about you.” Right. Could I say “We’ve heard so much talking (or perhaps speaking) about you” too? Does it sound either odd or redundant, by any chance?
Thanks a lot in advance. Cheerio
It sounds odd. You could say ‘We’ve heard so much that has been said about you’ but that would be redundant.
Hi Bev! Thanks a lot.
Take care 
“We have heard so much talk about you” implies that there is some sort of scandal or gossip that is making its way through the town.
Hi Luschen, nice to meet you. Thanks for your explanation.
