Alex Ferguson has ruled out any more summer signings at Manchester United and insists time is running out for any player looking to leave.

Ferguson unveiled Dutch defender Alexander Butt-ner yesterday, with the former Vitesse player having completed his move to United on Tuesday.

He follows Shinji Kagawa, Robin van Persie and Nick Powell to Old Trafford while Chilean Angelo Henriquez also completed a move to United this week.

But Ferguson insists that there will be no more incoming players despite rumoured interest in Mexico’s Hector Herrera. And time is also running out for Dimitar Berbatov, who is trying to seal a move away following the arrival of Van Persie.

Ferguson said: “We definitely won’t be buying anyone else, that’s for sure. There’s no movement I can tell you about.”

Van Persie made his debut in United’s 1-0 defeat to Everton on Monday night as a late substitute but Ferguson has revealed the Dutchman could start when United face Fulham at Old Trafford today.

The United boss admitted he would prefer the former Arsenal striker to have more games.

He said: “He’s had a few days training since Monday. In an ideal world he would be better with two or three games under his belt but it’s a home game and there’s every chance he could start.”

Danny Welbeck signed a new-four year deal with United and Ferguson revealed it was a difficult negotiation with the player’s agent, as the striker’s injury problems coming through the ranks were a concern.

But the United boss was relieved to tie the England international down.

He said: “It wasn’t an easy negotiation with his agent. It’s always difficult to assess their level at that age.

“Bearing in mind that Danny has had growth problems all the time, therefore he had a lot of minor injuries that sometimes kept him out for periods.

“Last season was exactly that. He had two injuries but he’s getting stronger and in two years he will be an outstanding player. We’re delighted to get him on a contract.”
