Champions League football resumes on Tuesday, with Robert Lewandowski's return to Bayern Munich with Barcelona being an obvious highlight.
Barcelona travel to Bavaria in a match few would be disappointed to see replicated in next year's final, with Atletico Madrid also travelling to Germany to take on Bayer Leverkusen.
After Premier League football was suspended at the weekend as a mark of respect following the death of the Queen, Liverpool are back in action against Ajax and are seeking to respond to a defeat to Napoli last week, while Tottenham travel to face Sporting CP.
Elsewhere, Inter face Viktoria Plzen after both sides lost their opening fixture and Eintracht Frankfurt, following defeat to Sporting, travel to Marseille – and the only remaining match of the day is Porto against Brugge.
For a closer look at all the action you can look forward to, Stats Perform has dived into the Opta data to highlight the most interesting facts for each match.
Bayern vs Barcelona
Scoring a hat-trick on his Champions League debut for Barcelona against Viktoria Plzen, Lewandowski returns to Bavaria with a devastating record this season and his goals in the 5-1 triumph saw Barcelona scoring more in one game than they had in their previous nine matches in the competition (4).
While that will give the visitors confidence, Barcelona have a poor record against the Bundesliga champions having suffered eight defeats in the competition to Bayern – twice as many as they have lost against any other opponent (4 vs Milan, Chelsea and PSG).
Four of those losses have come in the group stages, with Bayern winning both matches in 1998-99 and 2021-22 to boast a 100 per cent record against Barcelona in that regard, who have not lost more than twice against any other opponent in the group stage.
On top of that, Bayern have won 35 of their last 37 home matches in the group stages of the Champions League – the only exceptions being a 3-2 defeat to Manchester City in December 2013 and a 1-1 draw with Ajax in October 2018.
Liverpool vs Ajax
Liverpool won both meetings with Ajax in the 2020-21 Champions League group stages, the only campaign in the competition when they have met, with the Dutch side not beating Liverpool in any competition since a 5-1 win in December 1966.
Ajax's defeat to Liverpool in December 2020 is one of only two defeats that the Eredivisie champions have experienced in their last 25 matches (W13, D10) away from home in UEFA competition, the other being a 2-0 defeat to Getafe in February 2020 in the Europa League.
Having suffered defeat to Napoli last week, Liverpool are looking to avoid back-to-back defeats to start a Champions League campaign for the first time, while they have only lost their first home match in two of their previous 46 major European campaigns (W35, D9).
With seven Champions League wins in a row, Ajax travel to Anfield with a stellar run in the competition as only Bayern (8) boast a better winning streak currently.
Sporting vs Tottenham
While the two sides have never met competitively, Sporting are winless in all six of their Champions League matches against English opposition (D1, L5) and have lost all three of those games in Lisbon without scoring a single goal.
Tottenham's record against Portuguese opponents is scarce, winning against Pacos de Ferreira in the qualifying phases for the 2021-22 Europa League but not facing an opponent from the country in the Europe's premier competition since a 4-3 aggregate defeat to Benfica in the 1962-63 semi-final.
Sporting have never won their opening two matches in the Champions League, while Antonio Conte is looking to follow in the footsteps of Mauricio Pochettino as Spurs seek back-to-back wins to open a Champions League campaign for the first time since 2017-18 season under the Argentine.
Bayer Leverkusen vs Atletico
Neither side has a particularly good record to encourage them heading into Tuesday's tie, with Leverkusen having won just four of their last 20 Champions League matches (D8, L8), while Atletico have only kept one clean sheet in 21 away matches against German opposition in major UEFA competitions.
Atletico have only won one of four away matches against Leverkusen, a 4-2 victory in February 2017 in the Champions League, and have won only one of their last seven matches in Germany – though that was the match in 2017.
Late drama is to be expected whenever Atletico compete in the Champions League, with five of their last 10 goals in the competition coming in the 90th minute of matches.
Viktoria Plzen vs Inter
8 - Viktoria Plzen have won their last eight home European matches (including qualifiers), scoring at least twice in every win (21 in total). They have only lost one of their last 19 on home soil in European football (W16 D2), a 5-0 reverse against Real Madrid during their last UEFA Champions League campaign in November 2018.
2 - Since the start of the 2020-21 campaign, Inter striker Lautaro Martínez has scored just two goals from 48 shots (inc. blocks) in the UEFA Champions League. The Argentine’s shot conversion rate of 4.2 per cent (including blocks) is the lowest of any player to have attempted 30+ shots during this period.
Porto vs Brugge
3 - Porto have lost their last three UEFA Champions League matches, with two of those coming against Atletico; they have never lost four in a row in the competition before.
1 - In major European competition, Club Brugge have lost five of their six away matches in Portugal (W1), their one win coming against Sporting Braga in September 2011 in the UEFA Europa League.
Marseille vs Eintracht Frankfurt
15 - Marseille have lost 15 of their last 16 UEFA Champions League matches (W1), with the exception coming in their last home game in the competition in December 2020 against Olympiacos.
2 - Marseille and Eintracht Frankfurt will face in European competition for only the second time, also meeting in the 2018-19 UEFA Europa League group stages. Frankfurt won both matches (2-1 away, 4-0 home).
