The initial league meeting between the sides produced four goals as the teams played out a 2-2 draw. It’s likely that we get a similar volume of goals here with Watford seeing 2+ goals in each of their last five matches across all competitions, winning two of these games.

Watford have seen 45 goals across their 18 home games in the Championship this season, working out to an average of 2.5 goals per game. Only Leicester (4) and Sheffield Wednesday (3) have kept fewer clean sheets than Watford in the Championship this term, with Watford only managing to keep six shutouts in the Championship.

Wrexham have seen 2+ goals in four of their last five matches across all competitions, winning three of these games - including a 2-0 win over rivals Swansea last time out. Wrexham have avoided defeat in 13 of their 17 away matches in the Championship this term, with these games seeing 38 goals (2.23 per game).

Mikel Arteta has made Arsenal one of the toughest teams to beat at home in Europe, which is some achievement given the soft underbelly that Arsenal used to walk around with in the Champions League.

Arsenal have won 13 of their 16 home matches in the Champions League under Arteta, including all four at home this season. This has included notable victories against the likes of Bayern Munich and Atletico Madrid, in which Arsenal dominated and came away convincing winners.

Arsenal’s home form in the Premier League has also been very impressive with no side collecting more points at home than Arsenal in the top flight this term (38). The Gunners have won 12 of their 15 home matches in the Premier League, notably only conceding nine goals across these games.

Last week's first leg produced seven goals as PSG ran out 5-2 winners over Chelsea, and another frantic, open contest is expected at Stamford Bridge on Tuesday night.

Chelsea are yet to find the right defensive balance under Liam Rosenior, keeping just three clean sheets in his 17 games in charge. Both teams have scored in 12 of the 14 matches where Chelsea have failed to shut out the opposition, with only Arsenal and Newcastle preventing them from scoring in that period.

PSG will be more than happy to see this game played at a high tempo; they have the attacking quality to hurt Chelsea when the game becomes stretched. That's exactly what they did in Paris last week, with Dembélé and Kvaratskhelia in particular exploiting the defensive lapses Chelsea showed in that encounter.

The nature of the tie also points towards both teams scoring. Chelsea need at least three goals to level the aggregate score, and it's hard to see them managing that without leaving significant space for PSG's dangerous frontline - a group that has already demonstrated just how clinical they can be.

Leyton Orient are fighting for survival at the bottom of League One, and are playing like a side who desperately want to avoid the drop. Leyton Orient have managed to score in each of their last six matches - winning three and losing three of these games.

Despite being near the bottom of the table, Leyton Orient have managed to maintain a decent goal output - netting 49 goals across their 36 matches (1.36 per game), which is more than any of the bottom 10 sides in League One. Leyton Orient managed to score in a 3-1 defeat to Wimbledon earlier in the season, and have scored 22 goals across their 18 away games this term (1.22 per game).

Wimbledon aren’t in as much danger as Leyton Orient, but what has been a constant issue for the home side this season is keeping clean sheets. Only two sides have kept fewer clean sheets in League One this season than Wimbledon (7), with one of these sides being Leyton Orient (6).
