Swansea's manager, Alan Sheehan, expressed his satisfaction with the new signing, stating that Casey will provide additional competition and depth in the defensive area of the pitch.

Sheehan added that Casey is highly regarded at West Ham, having been part of their first-team squad during pre-season, and is eager to prove himself at the Championship level.

Richard Montague, Swansea's director of football, noted that Casey will bring valuable depth to the team in an area that needed additional resource this summer.

Montague also highlighted Casey's experience in Premier League football, which demonstrates West Ham's confidence in him, and his willingness to take on new challenges.
