Picking the Best Potential Wales Lineup to Face Spain on Thursday

Wales take on Spain at the Principality Stadium in a friendly on Thursday night, as they look to instil some confidence ahead of their UEFA Nations League encounter against the Republic of Ireland.

Ryan Giggs' men were beaten in their previous outing against Denmark in the Nations League last month, in what was Giggs' second defeat since his appointment in January. They put four past the boys in green prior to that match, but face a Spain side that sit at the top of their Nations League group after victories against England and Croatia.

Wales will also be without injured forward Gareth Bale, so it'll be a tough night and a good test. 

Here is their best potential line-up against the Spaniards. 

3. Goalkeeper & Defenders

Wayne Hennessey (GK): The Crystal Palace goalkeeper has had a difficult start to the Premier League. His side sit four points above the relegation zone, but the keeper has more than played his part in keeping the scoreline respectable for the Eagles this season. He's kept three clean sheets in the league from eight matches, pulling off some magnificent saves. He's conceded nine goals overall (the fifth lowest in the league) and despite being beaten at his near-post against Wolves on the weekend, he is expected to start between the posts against Spain.

Chris Gunter (RB): The Reading man, like Hennessey, hasn't enjoyed the best of starts to his league campaign - his side hover above the Championship's relegation zone on goal-difference. However, he possesses a wealth of experience and has 89 international appearances - three shy of Neville Southall's record of 92. He will be an asset against Spain and will be looking to get the better of their world-class full-backs.

Ashley Williams (CB): Williams has 80 international appearances to his name and his experience in the Premier League will undoubtedly help against their Spanish counterparts. The defender is a natural leader and his presence on the pitch will certainly be a bonus.

James Chester (CB): Chester has started all but one of Aston Villa's Championship matches this season. The Villa skipper has played the entirety of his first ten matches, but missed his side's trip to Millwall on the weekend through suspension. He has however helped keep one clean sheet for Villa and has a goal to his name, and may pose a threat from set-pieces. 

Ben Davies (LB): Davies has started six times for Tottenham in all competitions. He has found it difficult in recent weeks to cement a starting place ahead of Danny Rose, but will certainly be the main man for Wales. He faces a tough test against the Spaniards, but his experience in the Premier League and the Champions League will definitely help to put him in good stead against the former World Cup and European Champions.

2. Midfielders

Ethan Ampadu (CDM): Ampadu hasn't played regularly for Chelsea's first team but possesses several admirable traits. He is confident on the ball, reads the game well and knows how to pick a pass. He usually plays as a centre-half, but has been used in the past as a central-defensive midfielder. It depends whether Giggs will risk starting the youngster, but his energetic runs forward and his key recovering challenges make him a key candidate to start against Spain.

Joe Allen (CDM): Allen is an experienced combative midfielder. His time in the Premier League with Swansea and Liverpool helped him develop into a player that can read the game well and at Stoke City, he's learnt how to adapt his game and become more physical-minded, which will be pivotal in preventing the Spaniard's from developing any momentum.

David Brooks (RM): Brooks joined Bournemouth in the summer from Sheffield United and has featured in seven of the Cherries' eight league matches (starting all seven). The midfielder links up well with teammates and knows how to find the net, scoring twice (one in each of his last two games). He will be hoping to continue his fine run of form against Spain.

Aaron Ramsey (CM): Ramsey is one of Wales' most influential players. He has a lot of trickery, knows where his teammates are, can pick a pass and can find the net. He is a complete player. While talks of signing a new contract at Arsenal fail, the midfielder has done his talking on the pitch. He has been involved in four goals in the league, assisting three and scoring once. He was brilliant on the weekend against Fulham, where he scored and provided the assist for Pierre-Emerick Aubameyang, and will look to have a good game against La Furia Roja.

Harry Wilson (LM): Wilson has started seven times in all competitions for Derby County (on-loan from Liverpool). He is a player that possesses bags of ability, and has been involved in three goals all season. He has scored once in the league and been involved in two goals in the Carabao Cup, the last of which came in the Rams' victory against Manchester United on penalties. The winger cut-inside and sent in several dangerous deliveries before finding the top-corner with a terrific freekick and could be a key player against Luis Enrique's men.

1. Striker

Sam Vokes (ST): With the injury of Bale, Wales may look to Vokes for inspiration. The Burnley striker has two league goals to his name this campaign, and despite lacking the agility, pace and trickery, his movement and aerial presence could cause Spain a few issues. 

His two goals have come in the last two games and that may give him the confidence to extend that run against the Spaniards. He knows he won't see too much of the ball against Spain and will have to be clinical with any chance he gets.
