Portsmouth and Charlton Athletic are set to clash in a highly anticipated England Championship encounter. Portsmouth currently tops the league standings and remains undefeated this season, riding a wave of success with a five-match winning streak. Charlton Athletic also boasts an impressive record, having gone unbeaten in their last seven matches, with six wins and one draw, placing them among the top three teams. They've also maintained an unbeaten away record. Despite Portsmouth's overall stronger position, historical head-to-head results favour Charlton Athletic, who have remained undefeated in previous meetings. However, Portsmouth's home advantage isn't particularly strong, with only three wins in their last ten Championship home games, coupled with four losses. Their form has been further affected by a recent dip, securing only one win in their last seven league matches, indicating a decline in both attack and defense. Adding to their woes, key midfielder Tom Naylor is unavailable for the match.
