Barcelona is known for its lavish spending in the transfer market, and this January window has been no exception. The Catalan giants have already spent over €100 million on new signings, with some of the most expensive transfers in recent history.

One of Barcelona's key targets in January was Lionel Messi, who had been linked to Manchester City throughout the summer. However, after failing to agree terms with the Argentine forward, Barcelona turned their attention to other targets, including Paris Saint-Germain's Neymar Jr., Inter Milan's Romelu Lukaku, and Juventus' Paulo Dybala.

In addition to these high-profile signings, Barcelona also made several smaller deals, including the loan move of French defender Samuel Umtiti to AC Milan and the signing of Spanish midfielder Sergi Roberto from Bayern Munich.

Overall, it seems that Barcelona is making a significant investment in January, with the club looking to strengthen its squad ahead of the upcoming season. While the exact cost of these signings will be revealed in due course, one thing is clear - Barcelona is not backing down from its reputation as one of the world's biggest spenders in the transfer market.
