Messi struck a hat-trick in victory over Granada.
â€śItâ€™s unlikely that another player like Leo will play [this sport] and break this record,â€ť said Bartomeu.
"We have a fantastic player for many years to come. Weâ€™re privileged.â€ť
On Pep Guardiola's contract situation, Bartomeu added: "Heâ€™s an important person, he turned this team around, the Club and BarĂ§aâ€™s athletic vision. We want him to stay. He represents much more than a manager and we hope that he stays.â€ť
