Barcelona summer target and Arsenal full-back Hector Bellerin has fuelled speculation he could be heading back to Spain after reportedly buying a house in Barcelona.The 22-year-old signed a new long-term deal at the Emirates last season to ward off interest from Manchester City and the Catalan giants, who Bellerin left to move to London as a 16-year-old.Spanish outlet SPORT as per The Sun claim Bellerin has bought a property on the Catalan coast and that his parents who moved with him to London are set to move in.Reports suggest the defender is keen on a return to Barca, with new boss Ernesto Valverde looking to add another full-back to his ranks.Gunners boss Arsene Wenger will be desperate to hold on to his first choice right-back despite a dip in form towards the end of last season. The defender was dropped and replaced by Alex Oxlade-Chamberlain as the Frenchman switched to a 3-5-2 formation. Bellerin is currently with Spain Under-21s at the European Championships and featured in their 5-0 win over Macedonia on Saturday. After the win he was asked about his future, but refused to discuss a possible summer switch to Spain.Bellerin said:”I am totally focused on the Under-21 team and I do not think about anything beyond the European Championships.”Worrying for Wenger will be claims by Barca midfielder Denis Suarez, who is currently with Bellerin as part of Spain's Under-21's squad, suggesting the defender is torn about his next career move.Suarez told Mundo Deportivo: "I have spoken with Bellerin and on the one hand he wants to come back to Barca, but on the other he feels tied to Arsenal, I wish he could come."Meanwhile, Bellerin has vowed to pledge £50 to the victims of the Greenfell Tower fire for every minute he plays in Poland this summer.
