Sergio Busquets feels Xavi made the difference for Barcelona in their 1-0 La Liga win over Celta on Sunday evening.
The Catalans struggled in the opening 45 minutes at the Balaidos, but improved after the break following the introduction of the veteran midfielder in the 58th minute.
Xavi eventually provided the assist for Jeremy Mathieu's winner and Busquets had nothing but praise for his compatriot.
