Sheraldo Becker says Real Sociedad need to buy this summer.

Becker arrived in January from Union Berlin.

"To be honest, they need to strengthen with some players, they need to improve quality; but here I do get to play with all the midfielders who play for the Spanish national team," he said.

Becker admits he has hopes of eventually moving to Ajax.

“Ajax can always call me and then we'll see what happens," he added.
