Manchester United interim manager Ryan Giggs is unaffected by rumours which continue to link Louis van Gaal with a permanent move to Old Trafford.
Giggs won his first game since being put in caretaker charge following the sacking of David Moyes against Norwich City but reports suggest he could leave the club this summer upon the appointment of current Netherlands boss Van Gaal.
But the former Wales international insists he remains concentrated of the second game of his spell in charge of United against Sunderland.
"Nothing has changed," Giggs said.
"I'm here until the end of the season. My concentration is on the last few games. I've got a lot to think about, whether to carry on playing or not. My concentration is on the last few games. We'll see what happens at the end of the season."
Reports earlier in the week had suggested that striker Wayne Rooney could miss the visit of Sunderland with both a groin injury and illness, problems which are not expected to affect his fitness ahead of the World Cup.
But the England international is considered a doubt this weekend however United could yet be boosted by the return of Robin van Persie who has been missing with a sprained knee picked up against Olympiakos in March.
"A few of the lads have had a bug," the temporary United boss added.
"Wayne has and Anders [Lindegaard] has too. Wayne also has a tight groin. You have to be careful with the bug because the immune system is down a bit but Wayne, being Wayne, wants to play. We'll monitor it over the next 24 hours.
"Robin has been back training this week and has looked good. Whether tomorrow is too early, we'll just have to see how he goes today. He has looked really good this week."
