It's difficult for any team to maintain consistency every season in the UCL, unless they have extensive previous experience. PSG might be able to compete at least until the semifinal next season, but they'll be hard pressed to win the title again, as every team in the league is improving their performance by recruiting new players. This presents a major challenge for Enrique, despite the defeat to Chelsea. The coach feels strongly challenged to continue pursuing PSG best history.
Luis Enrique’s pattern has been studied that is why he lost to Chelsea.
Just as he use to study other teams pattern of play to play against them, his team play pattern has also been captured and if the term continue to play like that next season, they can’t make it to the semifinal you are even saying even though they can change some pattern of play, but as far as the players are the same, and the pattern of play is also the same, many teams will defeat them just as Chelsea did.
PSG needs reinforcements in some positions especially their central defense, they also need squad depth so that other players can also have some time to rest because they will still play more competitions next season, and the Champions League will be tougher than it was last season.
However, even in the League1, PSG needs to be very serious this time because they can’t keep dominating the competition every season, other teams are definitely preparing to compete against them, and Monaco is one of them which might surprise us next season.
