Veteran midfielder Paul Scholes believes the future is looking "healthy" for Manchester United following their summer signings.
United signed Robin van Persie, Shinji Kagawa, Nick Powell and Alexander Buttner before last week's transfer deadline and Scholes, 37, has been impressed by the quality of the new additions.
The ex- England international believes the Red Devils are stronger in every department as they look to regain the Premier League title, which they lost to neighbours Manchester City on the final day of last season.
And this strength in depth means underperforming players will face the axe with other players waiting in the wings, Scholes has warned his team-mates.
"You always like to see new players come in even if they're in your position because it's healthy for the team and exciting to play with the new players," he told Manchester United's official website.
"We've got strength everywhere in the squad. We've struggled with injuries to defenders, but when we have everyone fit I think there are two teams that the manager has available to him and that could compete in the Premier League and cup competitions.
"It all looks very healthy and, as players, we know when we get given our chance we have to take it. If you don't, you'll be out of the team, simple as that.
"All the new signings have settled in well. There's great competition for places with so many good players here and there are plenty of games to come for everyone to be involved in."
