What to watch out for in the Champions League

Cristiano Ronaldo is heading back to his alma mater but will have vie for top billing with a north London showdown, Marco Reus's potential return and Celtic's hopes of a fairy-tale repeat.

Ronaldo returns home
Needing two more goals to reach his century in UEFA club competitions (and with 95 in the UEFA Champions League alone), Cristiano Ronaldo is heading back 'home' to Sporting CP with Real Madrid this week. Where better to bring up a milestone than the club where he started his professional career? The 31-year-old's late free-kick helped turn round a match Madrid seemed destined to lose on matchday one before Álvaro Morata's added time header sealed a 2-1 win.

Reus fit to feature?
Unable to face Bayern on Saturday due to a heel problem, Marco Reus could make his long-awaited return from an adductor injury as Dortmund look to strengthen their grip on top spot in Group F. "It's a joy to see him in training," says coach Thomas Tuchel, with Reus yet to feature this season, and his extravagant gifts could prove valuable against a Legia side that has improved since their 6-0 matchday one loss to BVB. Jacek Magiera has replaced Besnik Hasni in the hot seat and, after their remarkable 3-3 draw with Madrid, the race for a UEFA Europa League berth remains on.

Can Leicester lift the trophy?
Prior to this season, Leicester had not won a single game in European competition since 1961. However, as Claudio Ranieri's side proved by winning the Premier League last season, the form book somehow does not apply to them. A draw would confirm their round of 16 place, and – with few expecting them to return to this competition any time soon – move them a step closer to the most improbable title success of all. Could it happen?

Sevilla out to scratch seven-year itch
Top of Group H and still unbeaten, Sevilla need just one point to reach the last 16 for the first time since 2009/10 – when they finished ahead of Stuttgart, Unirea and Rangers. Jorge Sampaoli's attacking juggernauts have won their last three games in the section since drawing a blank against La Vecchia Signora on matchday one. Beating the Italian champions would also confirm top spot – so what can possibly go wrong?

Spurs hoping to turn corner
Tottenham travel to Monaco having finally ended a run of seven games without victory when a Harry Kane double sparked a 3-2 comeback win against West Ham at the weekend. It was the club's first success in any competition since 2 October – and it could hardly have come at a better time, with Spurs needing all three points to bolster their Group E prospects. "It was fantastic to see Harry Kane score again," said manager Mauricio Pochettino. "For me, he's one of the best strikers in the world."

Arsenal and Paris drew 1-1 in September

Big guns meet in north London
Top spot will be the prize on offer when Arsenal reacquaint themselves with Group A rivals Paris Saint-Germain on home turf, having rode their luck before claiming a 1-1 draw in France on matchday one. That result left a bitter taste in Parisian mouths, but Unai Emery feels it will be a different story this time around. "There are things we will change, mainly because we are a better team now," said the Spaniard, who is hopeful Ángel Di María will be fit to feature. "It's a game with big actors, great football players – that's the beauty of it."

Atleti aim to bury derby gloom 
"Losing bothers me," said a rueful Diego Simeone after his Atlético side went down 3-0 in the Madrid derby on Saturday. "It's not good. I'm hurting for everyone." The pain of that result was acute, but the Colchoneros can pick themselves up by extending their record as the only team in the group stage with a perfect points tally. Already through following their last-gasp defeat of Rostov last time out, they will aim to make it five wins from five at home to PSV.

Watch Celtic's win against Barcelona in 2012

Celtic eye 2012 repeat
Celtic fans will be dreaming of a 2012 repeat when Barcelona come to town. It was a famous European night at Celtic Park in the group stage four years ago as goals from Victor Wanyama and Tony Watt sealed a memorable 2-1 victory. Brendan Rodgers, meanwhile, may still be having nightmares about his side's 7-0 loss at Camp Nou on matchday one. "You can park two double-decker buses in front of goal, but the world's best players always find the space," he said.

Maradona mark in sight for Napoli's Hamšík
Marek Hamšík has underlined his goalscoring credentials in November with goals against Beşiktaş in the UEFA Champions League and Lazio in Serie A – and for Slovakia against Lithuania in the European Qualifiers. Another strike against Dynamo Kyiv on Wednesday would move Napoli's captain level with Edinson Cavani in third place in the club's all-time scorers' list with 104 goals, and edge him closer to Diego Maradona's record of 115. The 29-year-old said: "I will never be like him, but beating his record would be special."

Şenol Güneş's art lesson
Beşiktaş welcome Benfica looking to leapfrog their fellow Eagles into the top two in Group B – and mindful that they will be through with a win if Napoli fail to beat Dynamo Kyiv. That would be an ideal scenario for Şenol Güneş, who raised a few eyebrows in Istanbul recently by making a bid to become the Henry Moore of football management. "I get asked what I do to mould players, but actually I don't do anything," he said. "I just scrape away their rough patches like a sculptor. Dealing with players and laying down principles in a team is the same as educating children. I think it's something I'm good at."
