De Gea was in excellent form in the first half and had it not been for him Everton could have been well ahead by the interval.
"We were the better football team, they had eight shots on target and De Gea did very well for us in that way," he told MUTV.
"But we had the possession and made some great openings without actually finishing it.
"That was the only difference. These shots on targets the goalkeeper did really well.
"Other than that we played good football, good combination play, on another day we would have won the match."
