For the majority of this season, it is Celtic who have been on the wrong end of upsets. So, it was a positive to see the Hoops pick up an unexpected win for a change.

On paper, one would not think that there is a world of difference between Celtic and Besiktas. But going into last night's game, there most certainly was.

Celtic had lost all three of their games in the Europa League and were sitting at 35th. They had also won just three of their previous ten matches in all competitions.

On the other hand, Besiktas had won two and drawn one of their three games in the Europa League, which was good enough to land them at 8th.

On top of everything else, Martin O'Neill ended up naming a weakened starting XI, which suggested that the focus had already turned towards domestic competitions after losing the first three Europa League outings. So, the win against Besiktas came as a surprise. Not everybody seems to believe that the Hoops were deserving winners though.

Leandro Trossard, who won the Premier League with Arsenal last season and joined Besiktas in the summer, is someone who seems to believe that the Turkish side were the better team on the night and deserved more.

While speaking on TNT Sports after the game, he said: "We controlled the first half especially, we were the better team. And then, obviously, we made a mistake in the second half, we gave the goals away too easily, I think. And then it was a bit of chaos for us. So, we need to be better because I think in general we played better than them, but we need to take our chances as well."

It would be safe to say that a lot of Celtic fans will not agree with Trossard there. It was a tight game throughout.

The first half ended 0-0 and one could argue that Celtic had the best chance of the first 45 minutes.

The game burst into life in the second half. Ultimately, Besiktas had more possession of the ball while Celtic had more shots on target, and eventually, more goals.

Following the substitutions, the Hoops were clearly the better team on the night. Obviously, Celtic won in the end and that is what matters the most. This is a result that they needed badly and somehow got when not many expected them to.

Now, it remains to be seen if they can turn their season around from here. The next game has taken on an added importance.

If Celtic can win that in a convincing fashion, it would give this team a fresh outlook and more hope going into the November international break. But if they drop points again, it will be back to square one in what has been a poor campaign so far.
