Barca go to Celta today.
Fontas said: "It's very special. It's the day you can catch up with former team mates and friends. You mark it down in the calendar. I look forward to it, but yes, it is a little strange.
"I am very happy here. I love the city, the club and the people. From the start, the coaches have put faith in me and that continuity gives me confidence and makes me feel good. That has been key because it was difficult after the injury with a loan spell at Mallorca. Here, everything has fallen into place."
