Wrexham's defensive frailties were laid bare for all to see as they suffered a 3-2 defeat at home to West Brom in the Championship on Saturday. As I caught a glimpse at the frustrated expression on the players' faces from my seat in the Macron Stand after the final whistle, it was hard not to wonder what the club's celebrity co-owners made of it all. Ryan Reynolds and Rob Mac jetted in for Wrexham's first home game in the second tier for 43 years and the pair were all smiles as they walked round the pitch before kick off. After notching an impressive three promotions in a row, manager Phil Parkinson has been well-backed by the two actors during the summer transfer window . High profile signings like Welsh international trio Danny Ward, Kieffer Moore and Nathan Broadhead have been made to help Wrexham compete in the Championship. Broadhead became the latest player to break the club's transfer record when his arrival from Ipswich Town was announced on Thursday in a deal reportedly worth up £10million. Most of the talk I heard in the city centre pubs in the build-up to the match was about the quality the 27-year-old forward would bring to the table. In fact, such was the buzz surrounding the move that even Deadpool star Reynolds admitted to ITV that he felt nervous before meeting him . Despite Wrexham suffering a late collapse in their opening tie away at Southampton last week, the co-owners must therefore have been excited to see what their money had bought. The early signs were promising as the Red Dragons looked like a team capable of giving an established Championship side a decent contest. Moore's performances have been an early highlight for Wrexham since the striker joined from Sheffield United for £2m , with his physical presence suiting Parkinson's system down the ground. He was lively in the early stages against West Brom, with former Sheffield Wednesday man Josh Windass providing the perfect foil alongside him up front. However, Wrexham were dealt a blow in the 20th minute as Isaac Price put the away side in front after Tom Fellows beat James McClean for pace on the wing. Ten minutes later, they suffered another setback as Windass had to be taken off with a hamstring injury. It meant Reynolds and Mac got the chance to catch a proper glimpse of Broadhead in action after he was brought on to replace him. Wrexham equalised shortly before half time as Lewis O'Brien netted his first goal for the club after the Baggies failed to clear their lines. And Broadhead came agonisingly close to scoring on his debut just after the restart as he fired a chance wide. That was as good as it got for Parkinson's side as mistakes at the back marred the occasion. There were groans around me as former Leicester goalkeeper Ward was beaten at his near post by Jed Wallace, who restored West Brom's advantage in the 74th minute. Ward was a surprise inclusion for the league opener against Southampton as many supporters expected Wrexham's established No. 1, Arthur Okonkwo, to start in goal. The ex- Arsenal youngster enjoyed a record-breaking campaign last season, managing 19 league clean sheets as his team gained promotion from League One . Ward, meanwhile, came with less than rave reviews from his time at Leicester. Wrexham were undone again seven minutes later following some suspect defending, as Price grabbed his second, heading home a cross from Mikey Johnston. There were gleeful chants of "F*** Hollywood" from the away supporters as they savoured the moment. Substitute Sam Smith grabbed a late consolation, but Wrexham are without a point on the board after their opening two games. For all the owners' spending, one area their team is lacking experience is at the heart of defence. Summer signing Conor Coady is the one exception, given his Premier League pedigree. But neither of the other two starting centre-backs on Saturday, Lewis Brunt and Max Cleworth, had played a single minute in the Championship before this season. Of course, it's still early days for Wrexham and with nine new faces, it was always going to take time for them to gel. There have been flashes of their potential, particularly in attack, meaning there's no need to press the panic button. Parkinson has plenty of credit in the bank and switching Ward for Okonkwo may solve some issues. However, the biggest worry is in defence, and I hope Reynolds and Mac flew home realising the need to shore up that backline. The West Brom defeat was a harsh reminder that errors will be punished heavily in the Championship. This is by far the biggest step up that Wrexham have made on their meteoric rise. Despite their significant outlay to date, the Tinseltown duo will still need to fork out more, especially if they want to turn their long-term ambition of reaching the Premier League into a reality.
