If it becomes apparent regular football is not on the agenda in pre-season, Wearside will be his first port of call.
Welbeck said: "I really enjoyed it at Sunderland.
"My main aim was to go there and get minutes under my belt in the Premier League.
"I did that and was a bit unfortunate to get injured midway through the season.
"That kind of hampered my form a bit, but overall I was delighted with it.
"You learn massive amounts playing regular Premier League football. It is an experience you cannot gain from being at Manchester United on the bench like I was the season before.
"Once I went to Sunderland and had the taste of playing games week-in and week-out I was happy with that.
"I am young and looking to improve and hungry for success as well, so playing week in, week out in the Premier League, that is a top way to benefit me."
