GORDON STRACHAN believes Celtic would top last season’s Invincibles clean sweep if managed a second successive domestic treble.
The former Hoops and Scotland boss insists improvements in other teams have made it a more difficult task this time round.
Strachan, who won three titles at the Parkhead side, said: “It’s been harder for Celtic this year.
“Neil Lennon has made Hibs a better side, Rangers are better this year and those two have made the league harder.”
Brendan Rodgers’ men retained the League Cup this season when they beat Motherwell 2-0, are one win away from a seventh consecutive Premiership crown and face Rangers in Sunday’s Scottish Cup semi-final at Hampden.
Hearts ended their record-breaking 69-match unbeaten run with a 4-0 win at Tynecastle at December while Kilmarnock also defeated the Hoops 1-0 in February.
Strachan added: “Obviously, you only need to look at Hearts, too, so the standard of the teams have made life a bit harder for Celtic and have pushed them a bit more.
“They had so many players at top form last year, but now you look at the big fella up front, Moussa Dembele, and Leigh Griffiths and they’ve both been injured at times this season.
“So, putting that all together, it would be a fantastic achievement if Celtic get the treble again as they’ve definitely been put under more pressure this year.”
