If it ain't broke, don't fix it.

This is a proverb that makes a lot of sense when you don't spend much time to really think about it. When you dig a little deeper, however, it's all a bit too simplistic.

If I own a car that successfully gets me from point A to point B then it doesn't need fixing because it isn't broken. But does that mean that I should just continue to drive it until it breaks down? I don't think so. It would be prudent to regularly take some time out for maintenance to make sure the car is in the best condition it can be at any given time. The engine running smoothly doesn't necessarily mean that I shouldn't replace the tyres, keep the oil levels topped up, or do some touch ups to the body work.

Today, I want to look at the idea that Jurgen Klopp doesn't need to do much work in the transfer window and give some reasons as to why I feel this is a flawed theory.

Okay, so let's get to the positive stuff. Liverpool have spent the last few years building a squad that has been able to compete both domestically and in European competition. Truthfully, there are very few players I'd want to be replaced in the first 11 because the players who could come in and make a real difference are generally not the kind that we would look to sign. Whether that is due to the pull of other clubs, transfer and wage demands, or even egos doesn't really matter. There are just some players who don't gel with the ethos of the club.

Nevertheless, Liverpool are now in a position where they have an opportunity to capitalise on what has been a great few years. Reaching 2 Champions League finals in a row and ultimately winning the latest one has put Liverpool back on the map. The world is watching and you can guarantee that players are interested in joining this project, fronted by one of the world's most exciting managers in Jurgen Klopp.

The club is also doing well financially, earning more from the previous season than any other English club, including Premier League winners Manchester City. Having been able to sell the likes of Coutinho for around £145M has meant that the signings of Alisson and van Dijk haven't had a major impact on net spend. Financial Fair Play isn't a worry here so Liverpool have quiet a lot of wiggle room when it comes to transfer fees at the moment.

So, what are the main issues that Klopp faces at the moment? Well, in my opinion, it is going to be very difficult to reach 97 points in the Premier League again next season. That's not to say that this Liverpool side won't be up there fighting for the title again, but to match a season where the Reds lost just once in the league is going to be a tough ask.

The reason that Manchester City have been so successful in recent years is the fact that their over the top spending has allowed them to create a squad that has very few weaknesses. Just think back to last season and how they dealt with injuries. If De Bruyne was injured for any other club then it would be seen as a disaster. Yet, Manchester City could simply turn to Fernandinho, another world class talent. Likewise, if David Silva is out of action then Bernardo Silva can step up with ease. It's this abundance of talent that allows Manchester City to rotate for freshness and navigate through injury episodes without falling to pieces.

Liverpool have had a couple of injury issues this season that have impacted on their campaign. Firstly, Oxlade-Chamberlain has been absent for the entire season and this put a lot of pressure on Keita to hit the ground running. As that didn't happen for the first half of the season, there was even more pressure on Liverpool's front three of Salah, Mane, and Firmino to come up with the goods. They certainly did that but you can't expect them to be playing at 100% all of the time.

Gomez also suffered from a broken leg which saw him out of action for a long time after putting in a great run of form alongside van Dijk prior to this. Thankfully, Matip came in and did a great job, but there is an obvious step down in quality between the players.

With Sturridge moving on after his contract finally expired, Liverpool are looking quite short on the bench. After Salah, Mane, and Firmino, all that's left is Origi and Brewster. The former has done a fantastic job but isn't at the required level to be a regular starter for Liverpool at the current time. The latter is a youth player with zero experience at Premier League level. Lallana also has long history of injuries and is now getting to an age where he would naturally lose some of his pace, if he indeed ever had any. Milner is a great asset to the team but you have to think that age will start to slow him down now that he is heading towards 34 years of age.

Ultimately, outside of Liverpool's first 11, there is a squad that can do a job but is nowhere near the level of Manchester City's which contains the likes of Jesus, Sane, Mahrez et al.

The idea that Jurgen Klopp should be happy with his squad is sound but it doesn't mean that he shouldn't be looking to spruce it up somewhat. Personally, I believe that Liverpool should be out there trying to sign a top class talent to fill in as a 4th in the attacking lineup. A player like Nicolas Pepe would be ideal in this situation. I also feel that another attacking midfielder such as Hakim Ziyech would really boost Liverpool's power in those areas. Just two signings of this kind of quality would push Liverpool to even greater heights.

This isn't about saying that Liverpool aren't good enough currently. It's about making the most of a positive situation and pushing on for either greater things. Whether the club acts on this or decides to go with what it already has remains to be seen. I believe this current squad can continue to win things but I do worry that a few injury issues could make things very difficult.
