BBC Scotland’s chief sportswriter Tom English has been answering your questions on Aberdeen.

Andrew asked: Assuming Celtic continue their impressive form in Europe into the new year, can Aberdeen take advantage of this in January? Should Dave Cormack get busy in the transfer market and get some cover in defence and midfield?

Tom answered: The goalkeeper and back four have started every league game. Sivert Heltne Nielsen and Jamie McGrath have started 10 of the 11 league games. Some of these guys are playing international football. So at some point they’re going to get tired and Aberdeen will need to have ones to step in there.

I think Cormack will add a bit. They probably could do with a bit of defensive cover. Jack MacKenzie has been very good. McGrath has been very good. Will they get offers for those guys? And I think Jimmy Thelin will probably be anticipating something because a lot of these players will have drawn attention from elsewhere, probably down south.

Celtic haven’t shown any sign domestically that Europe is bothering them right now. They’ll sign some more in January.

I don’t think that’s going to be an issue. I don’t think that’s going to bring Aberdeen any respite. They’re going to have to do it the hard way. And, you know, they’ve done it well so far.

Jack asked: Thelin and his staff have managed to work wonders with the Aberdeen squad this season, some who previously looked to no longer have a future at the club. Has there been any one player who has impressed you in particular?

Tom answered: It’s hard to pick out one player when they’re joint top at the table and unbeaten, going toe to toe with Celtic in the league, because it’s so impressive across the board. So you could start listing names here. Goalkeeper Dimitar Mitov has been excellent. The back four have played 11 league games in a row and they’ve been very, very solid.

McGrath has been excellent. Papa Gueye, out of the team now through injury, was excellent. He’s one of the renaissance stories, as is Duk.

Topi Keskinen has been good. Shayden Morris has been good off the bench. Ultimately, the one who’s impressed the most is Thelin because he’s the architect of all of this.
