After losing the EFL Cup final to Manchester City, Arsenal have the Champions League, FA Cup and Premier League still to play for.
Manchester City remain nine points behind Arsenal, though they have a game in hand against Crystal Palace as Mikel Arteta’s storm ahead of the top of the table.
The North London side face Sporting in the Champions League after clashing with Southampton in the FA Cup Quarter Final this weekend in their hunt for silverware this season.
Speaking to BOYLE Sports, who offer the latest football odds, Gallas revealed that despite Arsenal being in three competitions, they made only find success in one.
"Can Arsenal win the treble? I think Arsenal will win one trophy and that's the Premier League.
"They still have to be careful, but normally they would win the Premier League from this position.
"Champions League? I don’t think so. The FA Cup all depends on the result between Liverpool and Manchester City.
"If it’s Manchester City in the final, I think Manchester City will win. If it’s Liverpool vs Arsenal in the final, Arsenal will win. It’s a different style and I think Liverpool’s style suits Arsenal better."
No fewer than 10 Arsenal players pulled out of international duty in March as Arteta prepares his side to face Southampton after a two-week break from the EFL Cup final.
Reports have suggested that Arteta is simply resting his players ahead of the final stretch of the season as he tries to avoid further injuries in the chase for the treble.
