Everton boss David Moyes believes new signing Jo can make an impact at Goodison Park.
The Brazilian has struggled during his time in the Premier League with Manchester City but Moyes has predicted a change in fortunes for the striker.
"We looked at him last year but we weren't sure it was the right thing for us to pursue in the end," he told the club's official website.
"The truth is that it hasn't worked for him at Manchester City and there could be a couple of reasons for that, such as it takes time for some foreign boys to settle in.
"He might also have found the Premier League a bit of a struggle, but we're happy to give him a chance and it would be great if he could show the form he did in Russia.
"The players we have got here will make it easy for him to settle and he will have the support of everyone to ensure he gets back to his best."
