Declan Carroll has re-signed for Aberystwyth
The duo's arrival at Park Avenue will bolster Neville Powell's squad ahead of the Black and Greens' Welsh Premier League campaign, which kicks off in seventeen days time.
Walker was rated as one of the best right backs in the Welsh Premier League during three seasons starring as part of Powell's Bangor City side, making 61 appearances and scoring twice before a cruel injury curtailed his career at Nantporth in 2016/7.
Warrington-based Walker had previously represented the Republic of Ireland's Under 19's side and Wrexham in the Blue Square Premier League. He has been playing on trial during Aber's pre-season campaign and put pen to paper this week.
Carroll is no stranger to Aberystwyth supporters, returning for a second spell in Black and Green. A prominent part of Tomi Morgan's squad in 2012/13, Carroll has since gone on to strengthen his reputation as a superbly skilled midfielder with both Haverfordwest County and Carmarthen Town. He made 29 WPL appearances for Aber, scoring three times, as part of a career WPL total of 109 appearances and ten goals. He, like Walker, has appeared during pre-season for Powell's men and also signed on the dotted line this week.
