Champions League: Atletico's Haramball pro max and the fate of Liverpool

Arsenal, Liverpool and Barcelona all face big questions in the Champions League quarter-finals. One bad night changes everything.

It's the second leg of the Champions League quarter-finals across two grounds on Tuesday, while the other two take place on Wednesday.

Our focus is on the Tuesday fixtures, but it's impossible not to wonder whether Arsenal's season is about to crumble in one week or whether they will get a grip and make a semifinal appearance for the second season running.

It's also important to ask if Real Madrid can rely on its pedigree to advance to the last four with an away game to negotiate in Munich. 

They're playing against the pundits' favorite, Bayern Munich. Is there hope for Alvaro Arbeloa's side?

Tuesday games promise to be epic. Atletico Madrid rested their entire first eleven for their weekend game in La Liga. 

That act is an interesting signal from Diego Simeone as he intends to sit on their 2-0 lead from the first leg in Camp Nou.

Barcelona lost the first leg at home following a red card to Pau Cubarsi. 

The Catalonians dominated the game even with a numerical disadvantage, but they will have it all to do away at Atletico in the second leg.

The likes of Lamine Yamal and Robert Lewandowski will hope to inspire Barcelona to a comeback win over their fellow La Liga rivals; Simeone is known for strong defense and negative football. 

Are we about to see the mother of all "haramball"?

The second game of the night is in England, where Liverpool will hope to do what Barcelona is dreaming of. 

The Premier League champions lost in Paris 2-0, but they must be grateful to their luck that they're still in it.

PSG played Liverpool out of the park and tore the entire Liverpool team to shreds, but the reigning UCL champions couldn't score more than two goals. 

Poor finishing from the likes of Ousmane Dembele and Desire Doue means the game is still open.

Liverpool opted to rest the likes of Alexander Isak and Hugo Ekitike for their weekend win over Fulham. 

Now they must prove that they're not a spent force when PSG visits on Tuesday night. 

It's the only hope of silverware for Arne Slot; he cannot afford to perform like he did last week in Paris.

Liverpool set up to defend last week in the first leg. 

With two goals to recover and pride at stake, can the Liverpool players step up to the challenge in front of their Anfield crowd to serve us another memorable European night?
