Less than 48 hours after sealing Champions League qualification at Nottingham Forest on Sunday, the Blues squad began the journey from Cobham to the Polish city of Wroclaw.

It was straight to the Stadion Wroclaw, the venue for tomorrow's final, following Maresca and his squad's arrival, and the Chelsea head coach, Reece James and Levi Colwill undertook the pre-match media duties before an open training session was held.

That provided Maresca another opportunity to sharpen minds ahead of the clash with Betis, which the Italian insists has the full focus of everyone in his staff and within the squad.

He said: ‘The message over the last 48 hours has been, ‘We did something important [qualifying for the Champions League], but if we want to confirm that we are becoming an important club again, we need to show the desire to win the game and the trophy'.

'So it’s job done [in the Premier League], fantastic, and we’re happy. But tomorrow is a different game, a final, and we want to win at any cost.

'Every day we have something to prove, no doubt. What we have done [qualifying for the Champions League] is done. Now we have to prove ourselves again tomorrow.

'We have played many games this season in this competition, now we have just one more.

'For sure, for me personally [there is something to prove], but the message to the players is exactly same. Every day is a chance to improve, and we want to compete for titles.’

Maresca has named a 23-man squad for tomorrow's final. Christopher Nkunku is included in the travelling party after overcoming injury, while Nicolas Jackson is in contention to feature after missing the last two games of our Premier League campaign due to suspension.

And Maresca is confident the Senegal international is ready to deliver for the Blues if selected against Betis.

'Newcastle away was an important game, and he left his team-mates with ten players for one hour, Maresca reflected on Jackson's red card at St James' Park.

'He is a good guy, recognised his mistake and apologised with his team-mates, which was important. So, I am sure tomorrow he is going to do a very good game for us.’
