Tom English thinks Aberdeen gave Celtic much more of a challenge than what their city rivals Rangers did a few weeks ago.
The Hoops put the Ibrox side to the sword in a dominant 3-0 victory at the beginning of last month.

Goals from Daizen Maeda, Kyogo Furuhashi, and captain Callum McGregor helped the Bhoys blow the Gers aside, but yesterday, things weren’t as simple.
Indeed, the Dons defended resolutely and were clinical with the few chances they created.
Celtic were on the ropes at times, and although they should have won the game and were arguably masters of their own downfall, credit has to go to Jimmy Thelin and his side.
Post-match, English, chief sports writer for BBC Scotland, admitted that Aberdeen gave the Premiership champions more of a challenge than Rangers last month.
“Aberdeen’s performance today was streets ahead of Rangers’ performance against Celtic,” he said (Live on BBC Sportsound).
“There’s no comparison who caused you [Celtic] the more problems.”
A lot of noise surrounded Aberdeen and their impeccable run going into yesterday’s match.
The game at Parkhead was their first real test of the season, and they came away from it with pass marks.
The Dons caused Celtic problems on Saturday and will do so again at Hampden in a fortnight.
Currently, the Reds are the closest team in Scotland to the reigning champions, despite the Celts’ unfortunate failure to find a late winner yesterday afternoon.
