Pato sustained a sprained ankle that prevented him from playing for nearly two weeks, and has now returned to support Villarreal's attacking lines, reports Efe.
Bonera is back after a month on the sidelines due to muscular problems, just like his Spanish teammate Alvaro Gonzalez.
Currently Villarreal hold eighth position on La Liga table with five points, and are preparing for Swiss side FC Zurich in Group L of Europa League group stage, which also includes Turkish side Osmanlispor and Steaua Bucuresti from Romania.
