Taylor made his first senior appearance since his injury as a substitute for Ben Davies in a 2–0 loss against Chelsea on 28 April 2013. After the match, he expressed relief at his return to the first team. After Taylor's return, Swansea manager Michael Laudrup described the battle for the left-back slot between Taylor and Davies as "a beautiful problem for a manager to have". Following the transfer of Davies to Tottenham Hotspur in 2014, Taylor reestablished himself as first-choice left back for Swansea. Taylor signed a new four-year contract in June 2015, tying him to the club until 2019. After his position as Swansea's left back was challenged by Stephen Kingsley and Martin Olsson, on 31 January 2017 Taylor joined Championship side Aston Villa along with an estimated £5 million in exchange for Jordan Ayew. He made his debut eleven days later in a 1–0 home loss to Ipswich Town, starting and playing 77 minutes while wearing a protective mask over his fractured cheekbone. Manager Steve Bruce said he did well given his injury and lack of match practice. On 30 September 2017, Taylor was sent off at the end of a 1–0 home win over Bolton Wanderers for a foul on Adam le Fondre. Taylor was also eligible for India through his mother. He made his debut for Wales on 23 May 2010 in a friendly against Croatia at the Stadion Gradski vrt, replacing Andy Dorman for the final 23 minutes of the 2–0 loss; he and Mark Bradley had been promoted from the under-21 team in an emergency. In May 2011, he played two matches at the Nations Cup in Dublin. On 9 September 2014, in Wales' first match of UEFA Euro 2016 qualification, he gave away a penalty to Andorra in the fifth minute, converted by Ildefons Lima, but the Welsh fought back for a 2–1 victory. At the final tournament in France, he played every minute as Wales reached a tournament semi-final for the first time. He scored his first international goal in a 3–0 group win over Russia; it was his first senior goal since one for Wrexham at Grays Athletic in April 2010. Taylor was sent off on 24 March 2017 in a goalless World Cup qualifier away to the Republic of Ireland, for a foul that resulted in Séamus Coleman breaking his leg. Coleman needed surgery on a broken tibia and fibula after being injured in the match and Taylor was given a two-match international ban by FIFA.
