With the current attacking options, PSG will still be able to score that many goals, but when they are in doubt about winning and have difficulty breaking into the opponent's goal, they will be very frustrated, resulting in losing full points. Nice is a team like that and I often criticize the performance of their players because they are only able to score one goal and the most fearful thing is that when their opponents can turn things around then they have to be willing to lose full points.
Here Nice really feels the worst compared to PSG because the number of goal productivity is very small and that is not good for a team that is trying to compete for the title. They may have a strong defense and concede few goals, but there are times when they will face difficult phases that make their defensive laxity easy to break down. I think it is very difficult to find a competitor for PSG with conditions like that and still PSG will continue to dominate Ligue 1 regardless of which competitor is close to it.
Their game is always on the edge as as soon as they concede two or more goals, their whole game plan is in vain since they usually don't score more than one goal. But to be honest this isn't something that can quickly be fixed and if they only have the resources and players to focus on one thing over another, I think sticking to a strong defense is the best they can do. If they can then gradually improve their offensive game over time as well, then it is even better. But for the time being I believe Nice will remain the team scoring a low number of goals while also conceding not a lot of goals.
PSG having most lethal attack in French league and with this they can ruin any team, but their defense is also conceding goal which is also created problems for them but still currently they are at the top and having enough chances for staying at this spot but now Nice which is currently second but having the least goals in top ranks with just 19 goals from their 17 games mean they are not going to challenge leaders and if they want to have better in second half they need to improve this and having quality striker which will give them good confidence and improvement which is also important for them otherwise things can take good change, and they can go into problems with second half never been easy for any top team which is also wants to stay in touch for the European connections.
