United are in London for tonight's match.
Solskjaer told MUTV: "It's a big game of course, Chelsea have been third or fourth nearly all season so for us and the chasing pack they are the ones to catch. Hopefully we can get three points that will make a big difference for us going forward.
"Obviously he [Frank] was restrained because of the transfer ban during the summer window but I think we both believe if you give young players a chance, you know them and you know they will give you everything they've got and they might surprise other people. If you have a team full of energy and players who want to prove themselves it's great and Frank's done very well with the Chelsea team I think."
