Jose Mourinho says his goal in his first season as Chelsea manager is to re-establish the Blues as a genuine force on all fronts - and says he could look to sign a 'couple of players' this summer.
Chelsea announced Mourinho's appointment yesterday, with the "Special One' signing a four-year deal to return to the club he left in 2007.
Although Chelsea have won the league and the Champions League since his departure, they have struggled to make an impact in the title race in recent seasons.
A 6th place finish in 2010/11 was followed by 3rd spot this season but Mourinho, who won six trophies during his first spell at Chelsea including back-to-back Premier League titles, says the league won't neccesarily be his priority.
"In the last two years you were struggling in the Premier League. If you didn't win the Champions League you would be out of the Champions League this year," he told Chelsea's official website.
"This year you had to fight until the last match to qualify. We have to try of course to improve, but the priority in a club that reached the level is exactly that - improve individually, improve collectively and improve the structure of the club around the football team, and try to win the next match.
"Which one is the next match? The Premier League? Let's go for the Premier League. If the next match is the FA Cup, let's go for the FA Cup. It is difficult for me to say something is the priority. The priority is to work hard, work professionally and make the team better.
Mourinho is expected to spend big this summer and make some major additions to his new squad. Although the 50-year-old insists a splurge isn't on the cards, there should be some new arrivals at Stamford Bridge now his appointment has been confirmed.
"We have to improve the team, and when I say improve the team people are already thinking about how many millions Chelsea are going to spend, and when I say improve the team I am saying improving by work," he said.
My work has to improve players and improve the team. If I don't do that I am not happy with myself. If after that we can improve the team by buying a couple of players it is fantastic but I have to improve the team and the players with my work. That's a priority, improve."
