Solskjaer and Tuchel preparing to continue rivalry
Both managers have already met on four separate occasions in the UEFA Champions League when Tuchel was in charge at PSG.
Chelsea are unbeaten in eight matches in all competitions under new boss Thomas Tuchel and have closed the gap on their top four rivals in the Premier League.
United are second in the table -- six points and three places ahead of Chelsea -- but Solskjaer is not taking Champions League qualification for granted.
"I don't think the positions will be decided early," claimed the Norwegian. "We've seen teams going through bad phases, then a run.
"Our mentality is really good and we look forward to these games. We know Thomas has come in and it's changed a little bit at Chelsea and it's going to be a great challenge for us."
