Celtic's Champions League win over Ajax proves Dutch doubters wrong, says Virgil van Dijk Does the result against Ajax maybe prove those people wrong? Yeah, but that is not my motivation or what I am thinking about. I just want to play good games to help this club. We want to build a great season. As I said, before I came here, I knew Celtic was a top club. But the fans amaze me with the support we get. The European nights are obviously special, but they are also there in the league games. Helping Celtic to increase the two-point gap between themselves and Ajax with a victory in Amsterdam will also improve his prospects of being called up for the challenge matches against Japan and Colombia in Holland next month. "The talk about the national team was not on my mind before the game on Tuesday: not at all," he said. I've read and heard what has been said but I was not thinking about it. I was focused on my game and I just wanted to play a good game for myself, for the fans and for the club. I think we did well in the end. But, of course, playing international football is an ambition. It is always an ambition for every player competing at this level. You want to go as high as you can and also play for your national team. The Champions League is something that keeps you in the picture. It is the highest level of club competition and you always want to show what you can do in these games. Playing for Celtic should not be underestimated as this is a good club. But if things go well and we stay in the Champions League then that can only be positive. Self-doubt is a trait rarely displayed by Dutch footballers and Van Dijk is no exception. He is confident that Celtic can expect Europa League football, at the very least, after Christmas. "I think we have a good chance to go through in the group," he said. The two games coming up now - Ajax away and AC Milan at home - will be crucial. Tuesday night was a good start and those three points have given us something to build on. I think we have a chance to win again in Amsterdam. We know we have a lot of quality in the squad and that we can replace players when they are injured or suspended. Scott [Brown], Kris [Commons] and Adam [Matthews] are all very good players and we knew they would be a loss for us. But you could see the way other people came in to replace them. Look at Beram [Kayal], especially - he scored the second goal and that was very important. The atmosphere in Amsterdam will not be as intense as it is as Parkhead. But it is still a big stadium and their fans will give them good backing so it will be a tough night there. My record there in the Dutch league was not so good. I only won one match there and lost the rest but, hopefully, things will be different when I go there with Celtic.
