Barcelona president Josep Maria Bartomeu says they could yet buy again this month.

Barca welcomed former Bayern Munich midfielder Arturo Vidal as their latest signing earlier this week.

Bartomeu stated: "The transfer market ends on August 31st. In the meantime, we will remain vigilant.

"We are satisfied with the work of Grau, Segura, Abidal. We must be grateful. They do a good job.

"They have our support to do what it takes to improve our team."
