Barcelona have made two signings so far this summer, bringing in Pau Victor and Dani Olmo, but there are expected to be more incomings before the end of the month.
The Catalan outfit's financial situation means that there will also have to be departures, with a number of players being linked with exits.
Some big decisions will need to be made over the next couple of weeks, and with that in mind, Sports Mole looks at three players who could leave Hansi Flick's side before the transfer window closes for business.
Ilkay Gundogan | 33 years old | Midfielder

Gundogan was not involved in Barcelona's La Liga opener against Valencia on Saturday evening, with the midfielder, according to the club, missing out due to the head injury that he suffered against Monaco on Monday.
However, there is currently speculation surrounding his future, with the Germany international allegedly telling Barcelona that he wants to leave Camp Nou before the summer transfer window closes for business.
"I think that Gundogan will stay with us. He was not 100% fit to play today. He had some discomfort. I spoke to him, but that stays between us, not with you," Flick told reporters following the game with Valencia.
Gundogan has been linked with a move to Turkey, and his current deal is due to expire next summer, so it is not impossible to imagine the 33-year-old leaving over the next couple of weeks, but he would be a huge miss for the Catalan side.
Clement Lenglet | 29 years old | Defender

Lenglet is back with Barcelona after two seasons on loan in the Premier League with Tottenham Hotspur and Aston Villa respectively.
The 29-year-old was left out of the squad against Valencia, though, and he is not believed to be in Flick's plans moving forward.
Lenglet has another two years left to run on his contract, meaning that Barcelona are in a decent position to demand a healthy transfer fee, especially as the Frenchman impressed during his time in the Premier League.
Barcelona beat a number of clubs to the defender's signature in 2018, and he has made 160 appearances for the Catalan outfit in all competitions, but it does appear that the centre-back's time at Camp Nou is approaching its conclusion.
Vitor Roque | 19 years old | Forward

Roque arrived at Barcelona from Athletico Paranaense in January, and he made 16 appearances for the Catalan outfit in the second half of last season, scoring twice.
The 19-year-old's future is currently the subject of much speculation, though, with Barcelona not yet registering him with La Liga.
Roque was not involved against Valencia, and it is being reported that Everton are leading the race to sign him, with Marca claiming that the Toffees are in discussions over a deal.
Barcelona boss Flick has allegedly made the Brazilian surplus to requirements despite the fact that he has only just arrived, and it looks extremely likely that the youngster will be leaving Camp Nou over the next couple of weeks.
