Solskjaer said Friday that the Spain international has been “fantastic” for United this season, even though he has not kept a clean sheet for 13 matches.
De Gea’s deputy, Sergio Romero, is not available for the Huddersfield match after suffering a knee injury in training on Thursday.
A De Gea mistake led to the goal that allowed Chelsea to gain a 1-1 draw at Old Trafford last Sunday, with the goalkeeper spilling Antonio Rudiger’s shot, giving Marcos Alonso the chance to score with the rebound.
Failure to win that match has seriously affected United’s chances of securing the top-four finish they need to qualify for next season’s Champions League; they are currently in the sixth position, three points behind fourth-placed Chelsea with two games to play.
“He will play,” Solskjaer said of De Gea. “Sergio was injured yesterday (Thursday) and didn’t train. David’s been training well this week and he will play.
Solskjaer, a former United striker, gave De Gea a vote of confidence by adding: “Of course I trust him. He has been fantastic this season.
“Towards the end of the season, he’s been in headlines for the wrong reasons but he has to deal with that. A goalkeeping department are a fantastic group. They are such a tight-knit group.
“They have experienced better times than just now but David is ready for Sunday. David’s confident, and he is looking forward to the next few games. He wants to prove what a good goalkeeper he is. With the performances he has put in over the past few years, David has got all my confidence.”
However, asked if Romero might have started had he been fit, Solskjaer said: “It’s ifs and buts and hypothetical questions. Sergio knows how highly I rate him.”
