Barcelona sporting director Deco has broken his silence regarding the club's plans for Marcus Rashford, who is currently on a season-long loan from Manchester United. Despite the forward's impressive form for the Catalan giants, the former Portugal international stressed that any final decision remains pending due to various internal and external pressures. Speculation has claimed that Barcelona will activate the purchase option in Rashford's loan move to keep him at Camp Nou. Deco has been quizzed about the situation and explained what his thinking is with regards the England international. He told reporters on Sunday: "Rashford staying? We have a clear idea regarding Rashford and we know what needed to be done for him to stay.Expanding on the delay, Deco added: "But the matter is tied to financial fair play, priorities, performance, and the coach's decision, and it's something we haven't done yet because it's not the right time."
