The future of Frenkie De Jong and Pierre-Emerick Aubameyang remain uncertain, as they are being targeted by Premier League clubs.
Chelsea want both De Jong and Aubameyang, while Manchester United want De Jong.
United had seen a bid of up to £73m for De Jong placed on hold.
Xavi decided to use both players as substitute against Rayo Vallecano, but he maintained after the game that they are still in his plans, even though he doesn’t know what the final outcome of their future will be.
Speaking about the Dutchman after initially putting him on the bench for the Rayo game, Xavi explained: “Frenkie de Jong is not a reserve player, I’ve said that several times. He’s an important player for us.
“I don’t know what will happen, but if Frenkie stays he will be important to us. Just look at the situation he played in today.”
Probed on the futures of both Pierre-Emerick Aubameyang and De Jong, Xavi continued: “I am counting on him (Aubameyang). I’m really delighted with him, he can help us. Those I am not counting on already know, they know won’t play. Between now and 31 August, different things can happen, but I like Auba, he can help us.
“De Jong is the same as Auba, he is important for me. He’s in the squad and we will use him. I don’t know what will happen between now and 31 August, but not just with Frenkie or with Auba, with almost everyone in the squad.”
