This transfer did not come as a shock to anyone as Griezmann's move to the Camp Nou outfit was all but confirmed in May when Atletico Madrid released a video which confirmed that Griezmann wouldn't be plying his trade with the Wanda Metropolitano outfit next season.
The Frenchman's signing might seem like a real coup on the outside but there are a few issues which need to be addressed by the Catalan giants' management ahead of the next season.
We look at three major issues that Barcelona must address going into the 2019/20 campaign:
1. Positions and Formation
The main reason Barcelona wanted to add Antoine Griezmann to their attacking arsenal is his ability to score and create goals consistently whilst playing in multiple positions across the front line.
Though this might seem like a valuable trait, there is a downside to it. While playing under Diego Simeone and Didier Deschamps, he mainly featured as a second striker and occupied the same spaces for Atletico and France on the field as Messi has done for the Blaugrana for a lot of his career. Even though Griezmann is capable of playing as a left winger, some of his best moments have come while playing right behind or next to an out-and-out striker.
With the Frenchman's favoured position already occupied, Ernesto Valverde will have to figure out how to accommodate him alongside Messi, Luis Suarez, and possibly Ousmane Dembele and Philippe Coutinho in their starting lineup.
2. Recouping the Money Spent
Antoine Griezmann's arrival at Barcelona has taken their total spending this summer close to £196 million, with only £60 million coming in from the combined sales of Denis Suarez, Andre Gomes and Jasper Cillessen.
They still need to sign a back-up for Jordi Alba, a central defender and hold a strong desire to bring Neymar back to the club. Griezmann's unveiling as a Barcelona player has made balancing their books a necessity and all the more complicated. To sign Neymar, they will need to sell players to make the money available.
Recent reports of Barcelona having a debt of £800 million has raised concerns. Add to that their audacious plan to renovate Camp Nou and it seems like money will become an issue. The Catalan giants must find a way to generate money if they have to function smoothly and abide by Financial Fair Play rules.
3. Roles of Coutinho and Dembele in Question
Two of the most expensive signings in the club's history will have to settle for a role from the bench with the arrival of Antoine Griezmann. Barcelona have a real task on their hands as they need to figure out how to manage all their attacking players, having spent in excess of £300 million on signing them.
Both Coutinho and Dembele earn high wages, with the Brazilian said to be on weekly wages of £240,000 while the Frenchman is apparently making £220,000 per week.
The club definitely cannot afford to have two of their biggest earners sitting on the bench and a resolution over the futures of the two must be arrived at before the start of the new season.
