'It has to be that way. You have to be disappointed. The only thing you can do is understand the reason why. I will not be making excuses, as we know that we have to improve.[LNB]'I think we can improve and that is the positive thing for me. The reaction of the players has been very positive. As a fan or anyone close to the club, of course you will be disappointed that you are not winning. That's normal.[LNB]'But as a manager, you have to keep going, you have to keep working hard. That is the only way things will change. It's not been easy for us to be at this level but I know that we will improve.[LNB]'When I decided to stay (last March), I wanted to fight for this club. I signed a five-year deal. Sometimes there are good moments, sometimes there are bad moments but still I will fight. If we win I will be happier. If we cannot, we will fight until we win.'
