WROCLAW, Poland: Enzo Maresca said he had to convince his Chelsea players this season that the UEFA Conference League was the 鈥渂est competition in the world鈥� as he prepares his men to face Real Betis in Wednesday鈥檚 final.

The Premier League club are seeking to end their campaign with a flourish in Wroclaw after securing a Champions League spot for next season.

If they beat Betis in Poland, Chelsea would become the first club to win all four major UEFA tournaments, having previously won the Champions League, Europa League and the now-defunct Cup Winners鈥� Cup.

Maresca, in his first season as manager at Stamford Bridge, said had been forced to stress the importance of Europe鈥檚 third-tier club competition to his players.

鈥淧robably the most complicated thing this season about the Conference (League) has been to convince the players that for us it was the best competition in the world,鈥� he told reporters on Tuesday.

鈥淎nd the reason why was because it was the competition that we were in.鈥�

Chelsea are two-time European champions but have not won silverware since lifting the Champions League in 2021.

鈥淲e cannot play Champions League if we are at the Conference (League), or we cannot play Europa (League). We are in the Conference, so for us it was the most important competition, and we need to try to win that.

鈥淚f we are able to win, I think it鈥檚 a good thing, especially because we continue to build a winning mentality.鈥�

Chelsea have reached the final in eye-catching style, scoring a competition-record 38 goals so far and winning 11 of their 12 matches.

Maresca rounded on his critics after his youthful side secured fourth spot in the Premier League on Sunday with a 1-0 win at the City Ground, even using an expletive.

His team were within touching distance of eventual Premier League champions Liverpool in mid-December before stumbling badly, but results picked up again toward the end of the campaign.

On Tuesday he described Sunday鈥檚 eruption as an 鈥渙utburst鈥� in the heat of the moment.

鈥淔rom our point of view, they (critics) were not talking in the right way,鈥� he said.

鈥淎nd the reason why is because, yes, we are young, yes, we are the youngest squad in the history of the Premier League, but at the same time, they are men.

鈥淪o I also used what critics had said to say, 鈥楪uys, today (Sunday) is a chance that we can say that we are not young, we are mature enough, we can compete and we can do the right things鈥�.鈥�

The former Leicester boss said sealing a Champions League place for next season had been a huge relief.

鈥淲e feel much better,鈥� he said. 鈥淚 said a few times during the season that for me it was already a good season for different reasons.

鈥淚t can become a very good season if we finish top four, top five and if we are able to win the final tomorrow.

鈥淭he first target is there. We achieved that last Sunday and hopefully we can achieve tomorrow the second one.鈥�
