Krkic went on loan to Mainz in January as he struggled for game time under manager Mark Hughes, but the 26-year-old didn’t fair much better in Germany.
The Spain international made a mere 11 appearances for Mainz and contributed with only one goal. However, Scholes has faith in Krkic’s abilities and backs him to make an impact at Stoke once again.
“Bojan will return to us on July 1 and who knows? Bojan might be an absolutely key player for us next year,” Scholes told the Stoke Sentinel.
“Bojan, on his day, is as good as there is. He was a really important player for us. Perhaps he had his best days prior to his injury, best days for us that is.”
The forward scored four goals in the space of 11 games before suffering a cruciate ligament rupture in January 2015.
