Wrexham are currently preparing for a season in the Championship after they finished second in League One to earn promotion up to the second tier.

The Red Dragons are yet to make their first signing since the end of last season, but there will be plenty of work going on behind the scenes to identify targets to improve the team.

Phil Parkinson will have to judge which of his players are ready to make the step up to the Championship after a season in League One, which means that some difficult decisions could have to be made.

Why Thomas O'Connor may be replaced

One player who could be replaced as a regular starter is left-sided central defender Thomas O'Connor, who has been at the club since they were in the National League.

The former Southampton academy graduate has never played above League One level in his career to date, and was a regular starter - starting 25 of his 31 appearances in the 2024/25 campaign - for Wrexham this season.

O'Connor was, however, an unused substitute in five of the last seven matches and it remains to be seen whether or not he will be able to handle the step up to the Championship, a level that he has never played at before.

The BBC reported earlier this month that Wrexham, Norwich, Birmingham, and Sheffield United are among the teams interested in a deal to sign Harry Darling on a free transfer from Swansea City.

His contract with the Welsh side is due to expire at the end of this month, and the Red Dragons are one of the sides looking to snap him up for nothing.

Why Darling would be an upgrade on O'Connor

Parkinson must push to convince Darling to make a move across Wales rather than joining Birmingham, Norwich, or Sheffield United, as he would improve the club's options at the back.

Despite being right-footed, the 25-year-old Englishman often plays on the left-side of a centre-back pairing and this means that he could take O'Connor's place as the left-sided centre-back in a back three at Wrexham.

Unlike the current Red Dragons defender, Darling is an experienced Championship defender who has made 108 appearances at that level, which means that he would arrive at the Racecourse as a proven second tier star.

He would be a relatively risk-free signing as someone who has been there and done it and could immediately improve Wrexham's team, particularly when you take his performances this season into account.

As you can see in the table above, Darling's defensive work in the Championship, in terms of his success rate in duels and how often he was beaten by opposition attackers, was more impressive than O'Connor's was at a lower level.

This suggests that the Swansea star, who was hailed as "outstanding" by former boss Luke Williams, is a big upgrade on the current Wrexham left centre-back, particularly from a defensive perspective.

Darling also, as shown in the table, scored five goals from centre-back, compared to O'Connor's barren return in League One, and this suggests that he would offer a much greater goal threat in the 2025/26 campaign.

The English titan, who ranked in the top 31% of centre-backs in the league for progressive passes per 90 (3.70), is a ball-playing defender who has shown that he can mix technical quality and class on the ball with strength and reliable out of possession at Championship level.

Therefore, he would be the perfect signing, as a proven second tier star, to come in as a big upgrade on their left-sided centre-back position this summer.
