World record holders Katinka Hosszu, Florent Manaudou and Federica Pellegrini are bound for Glasgow after finding form at the inaugural ISL match in London.
Hosszu, 30, heads up a strong Hungarian squad with reigning 400m freestyle champion Boglárka Kapás and Ajna Kesely, a triple European long-course medallist at Glasgow 2018.
And the Iron Lady showed her steel at the London Aquatics Centre, digging deep to win the 400m medley on Saturday and then the 200m medley and butterfly on Sunday night.
With Minna Atherton within 0.2 secs of breaking Hosszu’s 200m backstroke world record, the four-time Olympic champion will be desperate to lay down more markers in Scotland.
Meanwhile London 2012 champion Manaudou took 50m freestyle spoils 0.2 secs ahead of Vladimir Morozov – a tantalising preview of their Tollcross clash.
The Russian, who won three golds at the last edition of the LEN Short Course Championships, also pushed Fabio Scozzoli all the way in the 50m breaststroke.
Eight-time European short course champion Scozzoli is another star to be confirmed for Glasgow, alongside compatriot Federica Pellegrini.
Italian Pellegrini didn’t have it all her own way in London, though, missing out to Femke Heemskerk and Kayla Sanchez in her signature 200m freestyle event.
And as the British team prepare to descend on Scotland, they stood up to the challenge of impressing a home crowd with a series of strong performances.
Teenager Freya Anderson, on the back of global relay bronze in Gwangju this summer, broke Fran Halsall’s ten-year British 200m freestyle record on opening night.
Stirling’s Duncan Scott, set to be one of the stars of EuroSwim, capped a brutal weekend of racing with a victory in the 200m medley, clocking 1:53.97.
Elsewhere, Scottish crowds can expect fireworks from prodigious Brit freestyler Anna Hopkin, who went sixth on the all-time NCAA list with a PB of 56.56 over 50m in Missouri.
