Kasper Hogh, Camilo Durán and Celtic's 10 summer signings graded

We are now in the second international break of the season, and we have had plenty of time to assess most of the Celtic summer signings.

The Bhoys are currently top of the Premiership, out of the Premier Sports Cup but with a chance of progressing in the Europa League, needing six or seven points from their last four games in the league phase of the competition.

Here we assess the summer signings at this stage of the season with school-style grades.

Hogh has largely been poor for Celtic. He his now three months without a goal, and despite putting in a decent performance over the weekend, we cannot pretend that the overwhelming evidence so far is that he has been a bad signing. He will get time to change that, but you can't sign a striker for £11million, see him not score for three months despite largely playing lesser opposition and pretend it has worked out.

Hassan has plenty of ability, but he is not as dangerous as he should be at this level, at least not consistently. He gets a C because he has shown flashes, but no better because we need to see much more of it.

Baur has been a real quality signing. He arrived for £4.5million and has looked like a player worth twice that. He has played out of position, and some of the issues there see him miss out on an A*, but Baur is a very good player who will continue to improve at only 22 years of age.

Duran gets the highest grade of the lot. He arrived for just £5.5million, hit the ground running and hasn't looked back. He has scored 13 goals and has clearly been Celtic's best attacker this season. Superb.

Van der Berg missed some time with injury, and he recently appeared for Celtic B, which looks to be his level at this moment in time. He is only 19 years of age, so we're not giving him an F as a player, he needs time to develop, but we have to consider that he was signed to make an impact now and he just isn't ready.

Lotomba started against Besiktas and conceded a penalty, but there were spells of the game where he did well, and he is only now getting match fitness after being signed last-minute. He could turn out to be a decent signing on a short-term deal. He certainly isn't a disaster.

Sorensen was signed on loan from Parma and was the best Celtic could muster up in the way of a replacement for Arne Engels. He is anything but. Sorensen looks particularly average and not good enough to start games in an already weak Celtic midfield. That isn't a good sign.

The truth is, Celtic didn't really need Mheuka between Hogh, Durán and Callum Osmand, so he hasn't seen much action. He has looked decent enough with cameos, but he might struggle for minutes during this loan spell.

Johnstone is starting to even out a little after a disappointing start, but he is a very average keeper at this stage of his career. Celtic needed better competition for Viljami Sinisalo, and they should have signed a younger keeper permanently who could offer that. They went cheap, and now they are considering starting a veteran loan keeper of a similar level to Sinisalo in front of him - answers on a postcard.

Again, Emenalo is a young player we have not seen a lot of. This grade isn't based on him as a player because we haven't seen enough. But the signing gets a D because Celtic needed a proper back-up for Kieran Tierney, and in big games, they are not going to turn to the 18-year-old Chelsea loanee, they will play Liam Scales, which says a lot about their failure to address this position.
