The January transfer window has come to an end and it's been a busy one in the world of football, especially at the top level. In Ligue 1, there were several blockbuster signings that caught the attention of fans and media alike.

One of the most significant deals of the window was the arrival of Lionel Messi to Paris Saint-Germain (PSG). The Argentine forward joined the French giants on a free transfer from Barcelona after spending his entire career at the club. He signed a five-year contract worth up to 200 million euros ($246 million), making him PSG's highest-paid player ever.

Messi's arrival was met with excitement across the globe, as he is considered one of the greatest players of all time and his addition to the squad will undoubtedly boost their chances of winning major titles this season.

However, not all transfers were as exciting as Messi's move to PSG. One of the more interesting deals of the window came when AC Milan signed Paulo Dybala from Juventus. The Argentina international joined the Italian giants on loan until the end of the season, with an option to buy in the summer.

Dybala has had a mixed start to life at Milan, scoring just two goals in nine appearances so far, but he is expected to make a bigger impact once the loan period is over and he returns to Juventus.

Another deal that caught the eye was the move of Kylian Mbappe to Manchester City from Monaco. The French teenager made his debut for the Blues during the final days of the window and showed why he is regarded as one of the best young players in the world.

Mbappe scored twice in three games during his time at Manchester City before returning to Monaco ahead of the new season.

Overall, the January transfer window in Ligue 1 was a successful one for many clubs, with some big-name signings being made. However, it remains to be seen how these deals will ultimately play out and whether they will have a positive impact on the teams' performances this season.
