In Amsterdam last summer, Poland finished top of the medal table and the strength of the team they have announced for Belgrade shows they mean business again.
Nine days before the start of the European Athletics Indoor Championships, the Poles have selected 34 athletes including Adam Kszczot, who is chasing his seventh major European title.
Back at the top of the European 800m rankings, Kszczot will be looking to win his third gold in this championship, having won the outdoor European crown for the second time in the Netherlands in July.
Kszczot, with a season's best of 1:46.17, was the indoor champion in Paris in 2011 and Gothenburg in 2013 in a career where he also won double European under-23 gold.
In his absence in Prague, Poland still took top spot in the event as Marcin Lewandowski triumphed.
This time he will run in the 1500m and their power in the pole vault will make Poland favourites for gold as Piotr Lisek, the world No. 1 this year with 6.00m, will be alongside 2011 world champion Pawel Wojciechowski (5.78m this year), with Konrad Bukowiecki among the favourites in the shot put.
Poland won 12 medals in Amsterdam – six of them gold – and Ewa Swoboda (60m), Sofia Ennaoui (1500m/3000m) and Kamila Licwinko, the 2014 world indoor high jump champion and 2015 European bronze medallist, will be their other big contenders.
The French team of 30 also includes a man looking to be back on the top of the podium in Pascal Martinot-Lagarde, the defending 60m hurdles champion, and the multi-eventer who could be the one to beat in the heptathlon, Kevin Mayer.
Could this be Mayer's golden time?
In the past four years he has won three major silver medals, including finishing a superb second in the decathlon at last summer's Olympic Games in Rio where he was so close to world record-holder Ashton Eaton.
As the American won with 8893, an Olympic record, Mayer was just 59 points behind, breaking the national record and showing his brilliant, all-round versatility.
And victory in Belgrade could be the start of a great year for him because with Eaton now retired, the decathlon world title will be wide open in London in August.
Morhad Amdouni, in the 3000m, Kevin Menaldo, in the pole vault, Jean-Marc Pontvianne and Melvin Raffin in the triple jump will also have major chances as will Floria Guei, the Amsterdam silver medallist, in the 400m.
She was part of the 4x400m relay team which won gold in Prague in 2015 and Agnes Raharolahy is back too as the French look to keep hold of that crown.
Switzerland's Selina Buchel produced a stunning run to win the 800m in Prague and she is part of a 14-strong Swiss team named for Belgrade.
Not among the gold-medal favourites beforehand, she won in 2:01.92 to beat Iceland's Anita Hinriksdottir and Great Britain's Jenny Meadows and this year she is second on the European rankings with 2:00.18 behind Poland's Joanna Jozwik who is not in Belgrade.
And the two-lap event should bring a medal too, as Buchel's teammate Lea Sprunger is the world No. 1 in the 400m with 51.46 from Magglingen at the start of the month, a time and performance which will make her rivals take real notice.
Nicole Buchler should have a say in the pole vault while at 20, Caroline Agnou, the European junior heptathlon champion, will be looking to make an impression at this senior level in the pentathlon.
But it will be tough, particularly with the presence of Olympic heptathlon champion Nafissatou Thiam, of Belgium, and also Nadine Broersen, the 2014 world indoor champion who spearheads the Dutch squad.
Broersen won gold in Sopot with 4830 points three years ago and will also be looking to make up for Prague where she had to retire after the high jump, the second of the five events.
Fellow multi-eventer Nadine Visser will compete in the 60m hurdles for the Netherlands while Thijmen Kupers, who won 800m bronze two years ago, will be eyeing a podium place again.
Meraf Bahta, the 2014 European 5000m champion, will run in the 3000m after breaking the national record with 8:43.00 in Birmingham last Saturday.
