The 19-year-old forward has been tipped to make a big impact at the Nou Camp in the coming years.
But first he will learn invaluable experience under Roberto Martinez at Goodison Park.
SunSport has gone back through the archives to come up with an XI of young players who came on leaps and bounds during temporary Premier League switches.
Birmingham from Manchester City, 2009-10
Made 41 appearances
ENGLAND’S No1 announced himself as a quality goalkeeper with a season in the Second City four years ago.
He scooped Brum’s Player of the Year gong, was nominated for the PFA Young Player of the Year award and was the stopper selected for the PFA Team of the Year.
Right-back: Kyle Walker
Aston Villa from Tottenham, 2010-11
Made 19 appearances
WALKER’S stint at Villa proved he had what it takes to thrive in the Premier League.
With the youngster’s pace, power and buccaneering runs down the flank, no wonder Spurs wanted him back as soon as the loan terminated.
Centre-back: Steven Caulker
Swansea from Tottenham, 2011-12
Made 26 appearances
AT 21, Caulker is far from the finished article.
But he has made a rapid rise in the last few years, even winning an England cap, with much of his progress down to his spell in Wales.
Centre-back: Jonny Evans
Sunderland from Manchester United, 2006-08
Made 35 appearances
THE Northern Irishman made a vast improvement during his two loan stints on Wearside.
Now an established defender at Old Trafford, he is surprisingly still only 25 but already has three Premier League winner’s medals on his mantelpiece.
Left-back: Danny Rose
Sunderland from Tottenham, 2012-13
Made 29 appearances
ROSE’S days at White Hart Lane looked numbered at beginning of last season.
But a terrific loan to the North East has kickstarted the youngster’s career, meaning he could well be remembered for more by the Spurs faithful than just a wonder volley against Arsenal.
Central-midfield: Jack Wilshere
Bolton from Arsenal, 2009-10
Made 14 appearances
ARSENE WENGER is the master of nurturing young players and knows just when to send them out to gain experience.
The Frenchman was on the money once again with Wilshere who went from promising youngster to Premier League star while at the Reebok Stadium.
Central-midfield: Alex Song
Charlton from Arsenal, 2006-07
Made 12 appearances
SONG has come a long way since a loan spell at across London at The Valley in 2006.
The Cameroon ace became a key player for Arsenal before moving on to Spanish giants Barcelona last summer.
Central-midfield: Tom Cleverley
Wigan from Manchester United, 2010-11
Made 25 appearances
CLEVERLEY is on his way to becoming the next big academy product at United and has the loan system to thank for it.
The England midfielder had spells in the lower leagues with Leicester and Watford before stepping up to the Premier League with the Latics under Roberto Martinez’s guidance.
Forward: Daniel Sturridge
Bolton from Chelsea, 2010-11
Made 12 appearances
NO wonder Sturridge finally walked out on Chelsea in January.
After eight goals in 12 games on loan at Bolton and some positive performances for the Blues, he still couldn’t get a look-in at Stamford Bridge thanks to the Fernando Torres love-in.
Forward: Romelu Lukaku
West Brom from Chelsea, 2012-13
Made 38 appearances
STEVE CLARKE pulled off a stunning coup when he landed Lukaku on loan last season.
The burly Belgian netted 17 goals for the Baggies and is still only 20.
Forward: Danny Welbeck
Sunderland from Manchester United, 2010-11
Made 28 appearances
NOW a regular in the England set-up, Welbeck owes much of his success to his time working under Steve Bruce at Sunderland.
The striker was given the chance to get to grips with the Premier League, scoring six goals and earning invaluable experience in the process.
