PSG handled the first half of the Champions League league phase perfectly, sweeping the first four matches with four wins, including two 4-2 wins against Manchester City and FC Barcelona, their two Pot 1 opponents. PSG also thrashed Villarreal (6-0) and Slovan Bratislava (6-1), their Pot 3 and Pot 4 rivals, respectively.

PSG still has to face their two Pot 2 opponents, AS Roma at the Parc des Princes on Wednesday, Nov. 25, and Aston Villa at Villa Park on Tuesday, Dec. 8. The two-time defending European champions will also take on Galatasaray (Pot 3) at the Parc des Princes on Wednesday, Jan. 27, a week after traveling to Como, arguably the best team in Pot 4.

This week, AS Roma, Aston Villa, Galatasaray, and Como had mixed fortunes in the Champions League. Here is the roundup:

PSG's next Champions League opponent, AS Roma, had 4 points before traveling to Old Trafford and quickly took a 2-0 lead. But as against Real Madrid last month, the Wolves collapsed late in the match, like former Marseille player Leonardo Balerdi, and lost 3-2. Third in Serie A, AS Roma are 20th in the league phase after four matchdays.

Roma's starting XI against Manchester United: Vasquez - Mancini, Hermoso, Balerdi - Rensch, Cristante, De Roon, Wesley - Mora, Malen, Soulé.

Top of the standings with PSG before this fourth matchday, Aston Villa lost 3-0 at Camp Nou on Tuesday night. Lamine Yamal took advantage of a gift from João Gomes in the 7th minute to open the scoring, and Raphinha then scored a brace in the second half.

Another defeat for Unai Emery against Barça with little consequence, as the Villans remain well placed with 9 points from 12.

They currently occupy 6th place in the standings and will travel to Galatasaray on Nov. 24 before hosting PSG on Dec. 8.

Aston Villa's starting XI against Barcelona: Suzuki - Cash, Lindelöf, Torres, Maatsen - Kamara, Gomes - McGinn, Manzambi, Buendia - Jackson.

It was the performance of this fourth Champions League matchday, along with PSG's match at Villarreal. Known for their fine soccer, the team coached by Cesc Fàbregas simply humiliated RC Lens, giving them a soccer lesson and scoring 9 goals.

It is the first time a team has conceded 9 goals at home in the Champions League. Thanks to this lopsided win, Como are 4th with 9 points and have the second-best goal difference in the league phase (+13), just behind PSG (+15). Bring on Como vs. PSG on Jan. 20!

Como's starting XI against Lens: Butez - Couto, Ramon, Kempf, Valle - Perrone, Milla - Da Cunha, Nico Paz, Caqueret - Douvikas.

PSG's last league-phase opponent, Galatasaray, made it two straight Champions League wins on Tuesday against Stuttgart, thanks to a brace from Russian attacking midfielder Aleksey Batrakov, who was reportedly on PSG's radar last summer but ultimately moved to the Turkish club.

With this second win (after the one against Lille), Galatasaray now has 6 points and climbs to 18th in the standings.

Galatasaray's starting XI against Stuttgart: Cakir - Sallai, Sanchez, Bardakci, Jakobs - Torreira, Lemina - Akgün, Batrakov, Yilmaz - Osimhen.
