When a club side finds themselves stacked in one particular position, they have the privilege to sell the excess personnel and bring in new faces. National sides, though, don't have any such privilege. The pool of players is generally altered if a youngster breaks through or a senior player retires or shows poor form. This certainly leads to some national teams being overloaded in one position, yet fragile in other areas.
One such side is England. The Three Lions have some serious quality at right-back and come Euro 2020, England head coach Gareth Southgate might find it extremely difficult to choose one from the options available. But, the good thing is that each one of England's right-backs is of a different breed, having specific skill sets and styles of their own.
Here, we take a look at England's options at right-back.
Kyle Walker
Kyle Walker is by far the most capped player on this list with 48 caps for England, and he has spent the entirety of his playing career in England being very well suited to the demands of English football. But for tactical reasons, Trent Alexander Arnold and Kieran Trippier were chosen ahead of him for England's World Cup squad in 2018 for the right-back slot, with walker playing as part of a three-man defence.
Walker's ability to run up and down the flanks with sheer pace and strength is a real asset for whichever the teams he plays in. He is an explosive fullback and arguably the finest athlete among all of England's current right-backs. His explosive strength, pace, and power often comes in handy going forward, and in terms of defending counterattacks as well.
His unique style and quality have been understated of lately, but he is probably the most balanced of all available options who could be a real weapon for England at the Euros if Southgate does decide to play him.
Trent Alexander-Arnold
Trent Alexander-Arnold currently plays for Premier League leaders Liverpool, and it is in the last one and half seasons that he really came to life in, and in the process, he equalled the record number of assists (12) in a single Premier League season last year.
He is a creative full-back and is by far the most offensively talented of all of them. He has exceptional crossing ability and vision, and basically, is like a No.10 playing in the wing-back position. The boy even has a powerful shot and an eye for goal in him.
Although Trent is the most impressive going forward, it is in defence, where he definitely has room for improvement. England may become susceptible to opposition attacks when he plays, but he will be an extra source of creativity from the wings if Southgate chooses to play him ahead of everyone else.
Aaron Wan-Bissaka
Aaron Wan-Bissaka caught the eyes of many when United forked out nearly £50 million for the former Crystal Palace full-back last summer, making him the club's fifth-most expensive signing ever.
In contrast to Trent Alexander-Arnold, Wan-Bissaka is a colossus in defence and is often unbeatable in one-on-one situations but in possession, he is nowhere near the Liverpool full-back in terms of end product and decisiveness on the ball.
Similar to Kyle Walker, Wan-Bissaka is excellent physically, gifted with superb athleticism. He is the Three Lions' best right-back in terms of defensive capabilities. The Manchester United man can put in timely tackles, mark opponents, and is almost indomitable and very difficult to get past for any winger.
Although he does need to improve his output going forward, his immaculate defensive ability could be a real weapon for England come Euro 2020.
Kieran Trippier
Kieran Trippier, who currently plays for Atlético Madrid is another one who possibly stands a chance of representing England at the right-back position in Euro 2020. The former Tottenham Hotspur right-back is an excellent crosser of the ball and a skilled set-piece taker.
In World Cup 2018, Trippier showed his superb ability playing at the right-back position for the Three Lions at the tournament. He even went on to score England's first-ever goal in a World Cup semi-final since 1990.
Trippier isn't as creative as Trent Alexander-Arnold nor is he as physically imposing as Kyle Walker, but, he is someone who comes in between the two, but he could come in very handy for the Three Lions at the tournament.
Reece James
Reece James is the latest Chelsea graduate to break through into the first team, and his crossing ability has already been likened to that of David Beckham's by Pat Nevin. The young Englishman is the latest addition to England's already impressive set of right-backs. Currently, he is having an impressive season with the Stamford Bridge outfit and is certainly a player to watch out for.
Although James is relatively young and inexperienced when compared to the aforementioned players, yet he could be the wildcard for England at Euro 2020 as he is impressive going forward and remarkably good defensively.
He is a player who is more than capable of making the right-back spot his own for many more upcoming years.
It remains to be seen as to who will be starting for England at Euro 2020, but one thing is for sure - Gareth Southgate has a very difficult job on his hands to pick the right player from an extremely talented set available to him.
