In general, if the witness statement is false in a material particular (and in the context of a case where you have no apparent defence and would therefore be pleading guilty, a material particular is anything that might be taken as an aggravating factor, the statement should be objected to) - although anything that is clearly an opinion of a non-expert witness (and therefore has no place in a statement of fact), can potentially be challenged without requiring the author to give evidence in person.
