Crosas is on the verge of moving to Parkhead after Barcelona recently agreed to sell to the Bhoys. And he could be joined by Venezuelan attacker Jeffren Suarez , who qualifies for Spain.

Meanwhile, Crosas said: "Football does not begin and end with Barca.

"I have finished that chapter in my life now because I have known from the start that they would not count on me. In the world of football you have to be intelligent and see how many players they have signed and what a great squad they now have.

"I only regret not being able to show if I had the quality, or not, to succeed there. You always think about making it into the first-team, but not everyone can do that and it is clear that things do not begin and end here.

"My aim now is to become the player I know I can be and then people will know if I could have succeeded at Barca."

Crosas has received numerous offers, but claims the work that Celtic put in to try and sign him swung his decision.

"The great interest from Celtic persuaded me," he concluded.

Jeffren, 20, is a Spain youth international and rated highly after a superb last season with Barca Atleti.
