We fell to a narrow 1-0 loss on the Premier League's opening day via Kyle Walker's own goal in the first half but gave as good as we got at Old Trafford.
We controlled the early exchanges and carved out the chance of the game in the fourth minute, created by Harry Kane and lobbed onto the roof of the net by Christian Eriksen.
United improved after their goal and the second half was even until we laid siege to the United goal late on with goalkeeper Sergio Romero saving well twice from Christian and once from Harry Kane.
"You’re never happy with a defeat but we have to be happy with how we played," said debutant Toby, who renewed his central defensive partnership with Belgian compatriot and former Ajax team-mate Jan Vertonghen.
"It’s always difficult at Old Trafford. We were right in the game, defensively we were strong and restricted them to very few chances which was good. If we keep at this level then the results will come."
As for his debut, Toby added: "It’s difficult to talk about yourself after a defeat.
"The stats say it all - we didn’t give them anything and defensively we worked very hard. We have to be confident for the Stoke game now and when we get our chances we have to take them."
