“As a Celtic player, you have to compete on both fronts, domestic and European. You’re judged in Europe, but you’re also expected to win every match in the league, too – and it doesn’t matter who is rested and who is playing.
“All of the players who are at Celtic are there for a reason – and that reason is they are deemed good enough to compete on both fronts. So, I wouldn’t look too much into people getting rested or being injured this weekend.”
Having managed Dundee United against Celtic seven times last season, McNamara knows all about the high-intensity pressing game favoured by Deila.
He rejected the claims of Malmo manager Age Hareide after Wednesday night’s 3-2 win for the Parkhead side that they lack complete fitness.
And, after tomorrow’s action on Tayside, McNamara will be hoping Deila has the last laugh on the veteran Norwegian coach.
He said: “I think that comment about fitness is maybe mind games. Celtic have won a lot of games in the closing stages over the last wee while.
“I watched the game on Wednesday night and Celtic started well. They got a couple of goals and looked strong against a good Malmo side.
“But then Malmo came back into it and it should be an interesting tie over in Sweden. Hopefully, for the good of Scottish football, Celtic can get through.”
McNamara, whose side could face ex-United stars Stuart Armstrong and Gary Mackay-Steven with Nadir Ciftci still suspended, added: “For me, it doesn’t matter who we are playing this weekend.
“But games at Tannadice against Celtic in recent years have not been too bad for us.
“‘We had the 2-2 match in the Scottish Cup last season that was quite an eventful game.
“They beat us 3-0 in the last game here in April, but, with the crowd behind us, hopefully we can do a lot better than last weekend.”
