Sainsbury's has cut its full-year sales forecast after warning that customers are likely to "spend cautiously" in the first few months of 2014.
Despite seeing record transactions in the run-up to Christmas, it now expects growth of "just under 1%".
The supermarket giant faces tough competition from the high-end Waitrose and discounters Aldi and Lidl.
On Tuesday, the two German-owned firms both said they had seen their best Christmas in the UK to date, although they did not release sales figures.
