Manchester United boss Jose Mourinho said that he would field a strong side when his former club Chelsea visits Old Trafford in the Premier League on Sunday.
Either side of this weekend's clash against the division's top side, United face Anderlecht in the Europa League quarter-finals.
With the Red Devils in fifth place on the Premier League table, four points behind fourth-placed Manchester City albeit with a game in hand, there has been suggestions that they should focus on gaining entry into the Champions League by winning the Europa League.
Mourinho, though, dismissed the notion, saying he will continue to try his best domestically until it is mathematically impossible to finish in the top four.
"When it is still mathematically possible to finish in the top four I think if we play against Chelsea with our second team you would kill me. The football country would kill me," the Portuguese told the media prior to Thursday's match in Belgium.
"There is no reason not to try while it's mathematically possible. If on a certain moment of the season we have no chances to get top four and we are still in the Europa League then nobody can criticise."
Meanwhile, Mourinho admitted that he hoped his squad doesn't sustain any more injuries as the season reaches its zenith.
"I hope we have no more injuries, no more suspensions," he added.
"I hope the players keep showing amazing character to keep going and going. Until it's not possible we are going to fight for the top four."
