Steve Bull: Jhon Arias is a dangerous forward that will improve Wolves

Some quality has left the squad and we needed to bring in some replacements and from what I've seen of Arias, he's quick and dangerous.

We've missed that pace in the side since Pedro Neto left and fingers crossed he can bring something different to the team.

Hopefully he can replace Matheus Cunha's role as the number 10, but of course it will be difficult to replace Cunha's goals.

He got 15 Premier League goals last season and those strikes more or less kept us in the league.

But we now have a new chapter and we have new players coming in to help this team.

Goals make games, but it all starts from defence. If you keep a clean sheet you always have a chance of winning a game.

I still think we need another experienced defender, to add to the attacking signings.

A Nelson Semedo replacement is a must and it won't be for a want of trying. The club will be looking around for the right player and hopefully someone who is as good as Semedo and Rayan Ait-Nouri.

I just wish the signings would come in soon, rather than when the season starts. Striking that balance is hard, you can't please everyone in football, and some fans are understandably frustrated.

Most clubs in the country, other than a select few that seem to be buying everyone, are finding it just as tough as we are to bring players in.

But Pereira has already spoken publicly about his commitment to the club and let's see what quality he has available to him at the end of the transfer window.

I think if he carries on the job he did last season, with the right signings, we have potential to be a good top half team next season.

We're all waiting to see who the next star will be, whether that is Arias or Fer Lopez.

Hopefully they have the quality we need to really impress, but Pereira won't rest with the team he has, he definitely wants more strength and depth in his side.
