If you play or watch football, you'll know that every match is different.

Sometimes players have brilliant games, and at other times, things don't go quite as well - which is all part of playing a sport.

But, is it OK to sub someone off early if they're having a tough game?

It comes after Tottenham Hotspur goalkeeper Antonin Kinsky was subbed off after just 17 minutes of their Champions League match on Tuesday, after the young keeper had made a mistake.

So we want to know what YOU think. Should a player be given more time to prove themselves on the pitch?

Or if they're having a bad game, should they be subbed straight away? Let us know in the comments below...

What happened during the Tottenham game?

Usually, substitutions happen later on in a match, when a manager wants fresh energy or wants to try a different tactic.

It's quite unusual for a player who isn't injured to be taken off in the first half, and that can feel difficult for the footballer involved.

During Tottenham's Champions League match against Spanish team Atletico Madrid, goalkeeper Antonin Kinsky had a very tough start.

The 22-year-old made a couple of mistakes early on in the game and Tottenham found themselves 3-0 down in the opening 15 minutes.

However, goalkeeper Kinsky - who hadn't played for the club since October - wasn't given time to get back into the game.

Instead, interim manager Igor Tudor, decided to make a change and replaced Kinsky with the team's usual first-choice goalkeeper, Guglielmo Vicario, after just 17 minutes.

Spurs ended up losing the match 5-2, with the second leg due to be played in North London next week.

The decision became a big talking point, with many people criticising the manager for substituting the player so early on in the game.

So, what do you think? Is it OK to sub someone off early if they're having a tough game?

Or do you think players should been more supported by their coaches, given that it was the manager who decided to field the player?
