Grioli’s transfer to Valletta is part of the deal which will take Brazilian midfielder Denni Rocha Dos Santos to Valletta.
Grioli, who is a product of Valletta but spent the last six five months on loan with the Rainbows, signed a three-year deal with Tarxien. Denni, on the other hand, had arrived in Malta in January 2009 after a long career in Brazil, Japan, Mexico and Australia. He therefore leaves Tarxien after spending the last 18 months with the club.
