The right-back registered five clearances, blocks and interceptions (CBI), seven recoveries and four successful tackles, supplementing this with two key passes and three open-play crosses. He also completed 82% of 52 attempted passes.
Jose Fonte (£5.4m) was awarded two bonus points thanks to a score of 28 in the BPS.
The centre-half produced five CBI, two recoveries and a successful tackle, in addition to completing 95% of his 40 attempted passes.
Bertrand registered six CBI and seven recoveries and Van Dijk chipped in with eight recoveries and five CBI.
The ICT Index
The Southampton playmaker supplied the assist for Charlie Austin's (£6.2m) winner and served up five key passes, three open-play crosses and two attempts on target.
He also produced more successful passes in the final third (21) than any player in the 1-0 victory.
Nathan Redmond (£6.0m) finished runner-up to Tadic in the ICT Index, scoring 9.4 to the Serbian's 13.5.
Handed another role up front by Puel, Redmond registered four attempts on goal - with three inside the box - and also created a quartet of scoring opportunities for the hosts.
Austin claimed third spot in the ICT. Emerging from the bench, he bagged the second-half winner and managed two of his four attempts on target.
The Scout Notes
Having scored a midweek Europa League brace against Sparta Prague, Austin could be in line for a second league start of the season in Gameweek 6, with Shane Long under threat.
Tadic has now provided points in each of the last two league encounters, yet with clashes against West Ham United, Leicester City, Manchester City and Chelsea in the upcoming five Gameweeks, interest in the Saints is understandably muted.
Further up the field, Fernando Llorente's (£6.3m) starting berth now appears in doubt after club-record signing Borja Baston (£6.9m) recovered from injury to be handed a debut as a second-half substitute.
