Ferguson, intent on redemption after United's humiliating pre-Christmas exit last season, will persist with a no-risk selection strategy in the hope of adding more points to the three collected against Galatasaray.
He said: "There's no chance I'll be going with kids in this one. We will play the experienced players.
"Cluj knocked out Basle over two legs in the qualifier - that shows where they are.
"To win in Braga takes some doing. It's not an easy place to go. We are taking it seriously.
"They think they can qualify now. They have a home game against United: get something from it and are in a good position with back-to-back games against Galatasaray next.
