Valencia rarely leave the field without conceding a goal. Especially given the fact they left a lot of emotion and energy in the Europa League games against Athletic Bilbao. So, you can expect a goal from attacking Celta. But Valencia are likely to score, too, given they have Negredo, Paco Alcacer, Santi Mina, Feghouli and others in the attack. So, BTTS sounds good enough. The season is almost over for Valencia. They are unlikely to get into the Europa League. They can now make amends to the fans and play good football.
Another option here is both teams to score and over 2.5 goals. If you want better odds, it’s sound to pick this.
