From your first link:
"A leading Premier League footballer arrested on suspicion of rape has been further arrested on suspicion of two incidents of rape against a different woman."
As he was arrested that means there are now 'active' 'criminal proceedings' against him within the meaning of the Contempt of Court Act 1981 (as amended).
Therefore reporting is now subject to the 'strict liability rule':
"it is a contempt of court to publish anything to the public which
creates a substantial risk that the course of justice in the
proceedings in question will be seriously impeded or prejudiced, even
if there is no intent to cause such prejudice."
Reporting Restrictions in the Criminal Courts April 2015 (Revised May 2016), Judicial College
Per the Contempt of Court Act there are four defences:
s3(1) "A person is not guilty of contempt of court under the strict liability rule as the publisher of any matter to which that rule applies if at the time of publication (having taken all reasonable care) he does not know and has no reason to suspect that relevant proceedings are active.
s3(2) "A person is not guilty of contempt of court under the strict liability rule as the distributor of a publication containing any such matter if at the time of distribution (having taken all reasonable care) he does not know that it contains such matter and has no reason to suspect that it is likely to do so.
s4(1) "a fair and accurate report of legal proceedings held in public, published contemporaneously and in good faith"
s5 "A publication made as or as part of a discussion in good faith of public affairs or other matters of general public interest is not to be treated as a contempt of court under the strict liability rule if the risk of impediment or prejudice to particular legal proceedings is merely incidental to the discussion."
Really the publication is mitigating its legal risk at the present time and it will no doubt report the name of the footballer if he is tried or does not proceed to trial.
