Welcome to the forum ally - bit of a random rant for your 1st post on the eve of possibly the biggest match we've been involved in for many a year but here's my thoughts (I'm off work sitting in the house bored)
I'm quite sure its not "bovril" made by bovril that is sold at FP-I think that its made by Knorr so that might be the difference but from wikipedia:
In November 2004 the manufacturers, Unilever, announced that the composition of Bovril was being changed from beef extract to a yeast extract, claiming it was to make the product suitable for vegetarians and vegans; at that time fear of bovine spongiform encephalopathy (BSE) may have been a factor. According to Unilever, "in blind taste tests, 10% didn't notice any difference in taste, 40% preferred the original and 50% preferred the new product"
You could always try what I do and mix 3 to 4 sashets of pepper in with it.
