All eyes is on an important round of continental clashes. A pair of compelling matches headline the schedule, as teams battling for important points in the group stage.
Which iteration of Chelsea will show up in Bergamo? Their last Champions League performance was a statement, a comprehensive three-goal win over Barcelona that stood as a high point for their manager's reign. However, form has been elusive afterwards. A credible draw with their London rivals was followed by a loss at Leeds, and a lackluster stalemate on the south coast means they arrive with momentum sapped.
They face a dangerous Atalanta who are tied in the standings alongside them. The Italian side suffered a heavy loss in their first game in Paris but have gone undefeated in Europe ever since, contrasting somewhat modest domestic form.
Similar to their London counterparts, Ange Postecoglou's side can be notoriously inconsistent. A 5-3 defeat in Paris, coming between disappointing defeats in the Premier League, piled pressure on boss the Danish coach. However, recent league results – a win and a draw available – have offered some stability.
This evening, they welcome a Slavia Prague side yet to win in the competition. This is precisely the kind of match that simply must be won if they are of climbing towards the knockout places, particularly given forthcoming challenges versus Borussia Dortmund and Frankfurt still to come.
The drama is not limited to England and Italy. One key encounter, Barcelona will look to bounce back from their defeat as they welcome the German side. Meanwhile, free-scoring PSV pose a major challenge for the backline of Atlético Madrid. Rounding out the night, AS Monaco hosts the Turkish champions in a match that has all the makings of a potential high-scoring affair. All matches begin at 8pm GMT.
A crucial evening in the group stage is upon us, as clubs striving to secure their path towards the knockout rounds.
