Manchester City have already won the EFL Cup this season and are battling Liverpool for the Premier League title.They are also still in the FA Cup and the Champions League.Liverpool can return to the top of the table if they beat Southampton on Friday night.And with City not playing in the Premier League this weekend due to FA Cup commitments, the Reds can apply the pressure on their rivals.Manchester City are favourites to win the league and FA Cup, while they are one of the frontrunners to clinch the Champions League for the first time in their history.And while Klopp admits Pep Guardiola’s men are at the top of world football right now, he is adamant that doesn’t mean they will win the lot.“If I was watching from outside, I’d probably say the same,” Klopp said when discussing City’s quadruple chances.“That’s how it is. You see City playing. How many people watch all 90 minutes of City games?“They won 2-0 against Fulham, we won 2-1 against Fulham because we made a mistake that we usually don’t make.“Both City goals against Fulham came from errors but well done in those situations.“If I was watching from outside, you’d think it looks like City can win all four (trophies) and I think the same.“If you’re with us you’d probably think that we can win both (the league and Champions League), if you’re not with us you probably don’t think it.“I’m not interested what people think, especially those who aren’t with us.“I don’t feel under-estimated or whatever. I don’t care.“I’ve said it a couple of times, City in the moment looks like the best team in the world. That’s how it is.“But that doesn’t mean that they will win all their games. I can imagine that people think that but it doesn’t make it more likely. I don’t care, I don’t bet, I’m not interested in odds.“I’m just interested in our football games and we cannot do more than win our games.”Indeed, Liverpool travel to Southampton on Friday having won their last four games.That includes three Premier League triumphs plus a 3-1 Champions League victory at Bayern Munich.Liverpool play Porto in the first leg of their Champions League quarter-final tie next week, before hosting Chelsea in the league.As for City, they take on Tottenham over two legs in Europe and their game in hand over Liverpool will be the Manchester derby on April 24.
