Solskjaer admits the arrival of Bruno Fernandes is a key in his team building.
“There were one or two pieces missing and we still know we miss one or two, to be where we want to be. It is a work in progress," said Solskjaer.
“Kieran [McKenna] and Michael [Carrick] are fantastic on the training ground, I have to say, and the boys are willing to learn.
"And now we have more and more fit players."
