On 31 January 2011, without having appeared for Barcelona's first team, Rochina joined Premier League team Blackburn Rovers on a four-year deal. On 11 February he scored twice for the reserves against Newcastle United's reserves, in a 4–4 draw. On 16 April 2011, Rochina made his league debut for his new club, starting in a 2–0 away loss against Everton. On 24 August he scored his first competitive goal for Rovers, just five minutes into the League Cup match against Sheffield Wednesday, and added a second in a 3–1 home win. Rochina scored his first league goal for Blackburn on 11 September, in a 1–1 away draw against Fulham. In the next game he provided an assist in a 4–3 home victory over Arsenal, and appeared in 18 matches during the campaign as the team was relegated. On 1 September 2012, Rochina scored a back-heeled goal to equalise six minutes from time in a 3–3 draw at Leeds United. He spent the second half of the campaign on loan at Real Zaragoza. He made his La Liga debut on 3 February 2013 as a 74th-minute substitute in a 1–1 away draw with Málaga CF, and scored his first goal in the competition on 27 April to help defeat RCD Mallorca 3–2 at La Romareda, as the Aragonese eventually suffered relegation after finishing bottom. On the opening day of the 2013–14 Championship season, Rochina dislocated his shoulder during the fixture against Derby County. After surgery, he missed the next three months of the campaign, and on 20 January 2014 he returned to the Spanish top flight on loan, this time to Rayo Vallecano. His first appearance came six days later, in a 4–2 home loss to Atlético Madrid in which he played 34 minutes.
Granada
On 3 August 2014, Rochina signed a four-year deal with Granada CF for an undisclosed fee. He scored two goals in his first year, the second being a 50-meter lob in a 3–0 away win over Real Sociedad. Rochina netted six times in 2015–16 as Los Nazaríes again avoided relegation, including a late equaliser for a 2–2 draw in the Derby of eastern Andalusia away to Málaga CF on 28 November 2015.
On 20 July 2016, Rochina moved abroad for a second time when Russian Premier League side FC Rubin Kazan triggered his €10 million release clause and offered to treble his wages – Blackburn were due 15% of the receipt. He returned to his homeland on 31 January 2018, joining Levante UD on loan until the end of the season.
Levante
Following his loan, Rochina signed a three-year contract with Levante on 4 July 2018.
