Speaking he said: 'This season represented a very good opportunity for Arsenal to become champions. They have lost their chance because they lost so many important points. It's very hard for both the players and the fans to see this opportunity fade away.
'The big teams - Manchester City, Manchester United and Chelsea - are not fighting for the title. With all my respect for Leicester City, who are doing fantastically this year, it's a big chance for Arsenal.
'If you ask me what is wrong, it's difficult to say. Arsenal are too far behind to win the league. Wenger works very hard. You cross your fingers that Leicester lose some points.
Wenger is under intense scrutiny after another season that promised so much appears to be leading towards familiar disappointment - but Gilberto maintains the Arsenal manager is still the best person to take the club forward.
'The results are not coming and everyone at Arsenal and all the Arsenal fans want the club to win the league again. After such a long time, this was their chance but they are far behind in the league.
'Wenger is very aware of what he has to do for the team but it's hard to remain stable when the results don't come. Arsenal must find a way to get results but it is tough.
'Sometimes people are too hard on him. They forget what he has done over the last, almost, 20 years for the club. They should think a bit more. We all accept criticism but you shouldn't go over the top. Wenger is a very intelligent and capable man. He knows how to deal with this pressure.'
