(CNN) After a week in which football has redefined the word "incredible," the Premier League title race enters the final chapter of an extraordinary season.

Reigning champion Manchester City, the odds on favorite, will retain the title should it defeat Brighton on Sunday. Should Pep Guardiola's men triumph at the Amex, then that is it. City is the Premier League champion.

But in a week in which City's chief rival Liverpool qualified for the Champions League final in the most dramatic of circumstances, and Tottenham stunned European football with an astonishing comeback win at Ajax , you can perhaps forgive City fans for feeling slightly apprehensive.

Liverpool boss Jurgen Klopp celebrates his side's win over Barcelona with his players.

To that end, the Premier League has confirmed that two trophies will be on standby for Sunday, just in case Manchester City fails to beat Brighton and Liverpool is crowned champion.

The 'Champions Trophy', which has been sitting in City's trophy cabinet all season, will be brought to Brighton for Guardiola's team to lift should it be triumphant. A second trophy, identical in appearance and with an engraved base detailing past Premier League champions, will be at Anfield for Liverpool should it provide the venue for yet another remarkable chapter in the club's history.

Vincent Kompany and Sergio Aguero of Manchester City lift the 2018 Premier League trophy.

Still, Brighton, one place outside of the relegation zone, have offered little in way of a scare factor for a City side that defeated the south coast club in the FA Cup semifinal last month. For Brighton, without a win in eight league games, the only highlight being a draw away at Arsenal, the season is all but over after narrowly escaping relegation.

But should Brighton decided against a day trip to the beach and instead gain a result against City, then the Premier League title could be off to Merseyside.

If Liverpool, fresh from that astonishing victory against Barcelona, wins at Anfield on Sunday then it will finish the season with 97 points -- the highest any team in second has ever achieved. Even more galling is the fact that should it avoid defeat against Wolves, it would have lost just one league game all season.

Divock Origi of Liverpool (27) celebrates as he scores his team's fourth goal against Barcelona with Xherdan Shaqiri.

Both City and Liverpool have been exceptional, but only one can become Premier League champion. So far, the lead at the top of table has changed hands 32 times ... only Liverpool can make it 33.

Here's how the great battle between two of England's and Europe's most in-form clubs unfolded.
