Jonathan Legear has had his contract at Blackpool terminated by mutual consent.
Midfielder Ben Watson admits he jumped at the chance to join Watford's promotion push, after joining from Wigan.
Chelsea will underline their desire to win more silverware next season by going on a £100million spending spree, according to Rafael Benitez.
Benitez's interim spell in charge of Chelsea is ending on a high after the Spaniard's team beat Benfica 2-1 to lift the Europa League trophy in his penultimate game in charge.
After inheriting a team short on confidence after their embarrassing early exit from the Champions League, Benitez leaves Chelsea in a healthy state despite having to endure taunts from Blues supporters during his six-month reign.
Jose Mourinho is the overwhelming favourite to replace Benitez this summer, with the Portuguese expected to sever ties with Real Madrid.
And the 'Special One' looks set to have plenty of money at his disposal if he returns to the club where he enjoyed so much success from 2004 to 2007.
"Chelsea will be much better next season because they will spend £100million and they will sign three or four players," Benitez told Spanish radio station Onda Cero.
"They have good young players like (Victor) Moses, (Eden) Hazard, Oscar, (Cesar) Azpilicueta, David Luiz, Fernando Torres, Oriol (Romeu), they are all improving and they all have potential.
"The foundation is already there. The future is bright for them."
Speculation has intensified that Mourinho will go back to Chelsea after he declared that he wanted to manage at a club where he "is loved" following a turbulent two-year spell in Spain.
Right-back Paulo Ferreira was one of the players Mourinho recruited as part of a big spending spree following his appointment as Chelsea boss nine years ago.
The 34-year-old, who also worked with Mourinho at Porto, thinks everyone at Chelsea wants to see the charismatic coach return.
"It's not just me, I think everyone (wants to see him come back)," Ferreira said.
"This means titles and that is what the club wants. Nothing is better than him."
Chelsea goalkeeper Petr Cech thinks Mourinho's return is almost inevitable.
"There is a big probability that it can be Jose," he said.
"He has a fantastic history with the club, the supporters love him, and he would be good for the players, obviously."
Despite all the clamour for Mourinho's second coming at Stamford Bridge, the Chelsea squad are by no means eager to see the back of Benitez.
It looked as if Benitez's appointment as interim manager had been a mistake when he failed to win his first three matches, but the Spaniard has restored calm and consistency to the Chelsea squad amid a backdrop of strong criticism which sometimes boiled over into hate.
'Rafa Out' banners and signs branding Benitez as a 'Fat Spanish waiter' were often seen during the opening stages of the 53-year-old's reign due to his association with the club's rivals Liverpool.
To lambast a man who has won two Spanish leagues and a Champions League trophy in such a way was too much for Ferreira.
"A lot of supporters have not been fair with him, and sometimes I think they should think more about the team than the manager," he said.
"He has given his best even though he knows he is going to leave at the end of the season."
Benitez is expected to join Chelsea's players in a lap of honour following their last game of the season at home to Everton on Sunday.
When asked whether the fans owe Benitez a thank you, Ferreira said: "I think they should. He gave a trophy to the club so he has credit for that."
Ferreira was not the only Chelsea player who went out of his way to praise Benitez following the win in Amsterdam, which came courtesy of Branislav Ivanovic's 93rd-minute header.
Petr Cech said he thought Benitez deserved a winner's medal after his work with the squad while defender Azpilicueta underlined his admiration for the coach when he said: "We have won this trophy for him.
"I am very happy with him because he gave me a lot of confidence. I have learned a lot from him."
The strongest praise came from David Luiz, who revealed that Benitez drove Chelsea to victory following an inspirational half-time team talk.
"In the first half they controlled the game and the second half Rafa spoke with us. He changed some positions, he told us 'if you want to win this competition you need to change' because the guys were too slow. That's why we won. Everything (is down to him)," the Brazilian said.
"Many people have said bad things about him this year. He is a professional guy, he has a lot of character, he supports everything and he deserves a title."He is a fantastic coach. He helped me a lot."
