Manchester City star Kyle Walker says all the players at the club must give manager Pep Guardiola a selection headache.

The Citizens have now won 15 games in a row domestically this term.

Guardiola has heavily rotated his starting lineups during that run, ensuring no player is burnt out as the season reaches its climax.

"I've said it many times before, I would hate to be this manager because of the headache we must cause him," said Walker, per the Daily Mirror.

"Every 11 that he puts out seems to put a good performance in. But it's a good problem to have and shows the level of where this football club is moving.

"Whoever is named on the team-sheet needs to put in a good performance and put pressure on those who are starting now and hopefully give the manager something to think about.

"We want to achieve great things here and hopefully we can do.

"The level we have set ourselves this season, definitely over the last couple of months, have been extraordinarily high.

"If we were to let our standard drop, it wouldn't be doing ourselves justice.

"Each and every game, we approach it like it's our last. We change nothing and we do nothing different.

"The manager prepares just the same, whether it's Swansea or Liverpool, everything is done in detail to give us as much information as he can before we go out on the field."
