Paul Scholes has hailed the impact of Manchester United's new signings and admitted he is wary of the competition for places in the side.
Scholes, 37, came out of retirement mid-way through last season to play an important role for United as they pushed rivals Manchester City all the way in the title race, only to miss out on goal difference.
The midfielder signed a new one-year contract at Old Trafford in May, and he has reiterated his importance to Sir Alex Ferguson's team already this season, most recently helping to inspire a 3-2 comeback at Southampton.
Ferguson has brought in Robin van Persie, Shinji Kagawa, Nick Powell, Alexander Buttner and Angelo Henriquez this summer, and Scholes has welcomed the competition for places.
He said in the Daily Star: "You always like to see new players come in, even if they're in your position. It's healthy for the team and exciting to play with the new players. We have 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 the manager has available to him 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."
Scholes went on to hail the new recruits, adding: "All the new signings have settled in well. Shinji has been with us since the start of pre-season, so he's had a good amount of time. He's a top-class player who did great in Germany and we're lucky to have him.
"Shinji is just a clever footballer who gets into those great positions where it's difficult for other teams to pick him up. He's always on the move, which makes it easier for the midfielders to find him.
"He fits in with the way we play. It's important he links up well with the midfielders and centre-forwards and he's shown he's clever enough to do that. He's intelligent and someone we all really enjoy playing with.
"Nick Powell has done well. He hasn't had much first-team action yet but there's plenty of time.
"Robin is a top signing and we hope to form a good understanding with him as the season goes on.
"Alex played his first game for the Under-21s last week and did well. There's competition for places, with so many good players."
