Celtic transfer window review, part one: Kyogo Furuhashi, Carl Starfelt and Liel Abada - Ross Goodwin

With three of those - Cameron Carter-Vickers, Jota and Giorgos Giakoumakis - arriving on deadline day alone, there is plenty to get excited about as Ange Postecoglou continues to mould the Hoops into the team he wishes them to be.

Here, Ross Goodwin of Bhoys Analytics gives his verdict on Celtic's summer acquisitions in part one of his transfer window round-up...

Kyogo Furuhashi scores against Dundee

Kyogo Furuhashi

The Japan international came in with many wondering if he could make the transition from the J1 League to the Scottish Premiership due to the stylistic differences between the leagues.

If anything, Kyogo has proved that the J1 League is a market Celtic should be scouting extensively for reinforcements come January when their season ends. Postecoglou has said as much and I’m excited to see what other hidden gems he brings to Scotland.

There was concern about Celtic’s ability to replace Odsonne Edouard but in Kyogo they have found a player near his peak that is more suited to the manager's system, which is phenomenal recruitment.

His constant movement and relentless pressing make him an awful prospect for defenders to deal with, as he consistently generates clear-cut opportunities for himself.

Kyogo is only 620 minutes into his Celtic career and has already scored seven goals. When looking at expected metrics it’s even more promising as his xG is 0.9 and xA is 0.2. If he can keep these numbers up across the season, we can expect a huge goal return.

Ultimately, Celtic have found a striker who looks to be comfortably the best in the country already - which going into the window wasn’t something I was expecting. An absolutely fantastic signing.

Carl Starfelt, right, joined from Rubin Kazan

Starfelt has had a more difficult time than the attackers in adapting to what Postecoglou expects from his defenders - which is a lot, especially on the ball.

A few high-profile errors such as against Hearts and AZ Alkmaar had fans questioning the signing. However, not all players adapt instantly to new teams and they can often take months to regain their form from the club they were signed from.

In Russia last season, Starfelt’s defensive and aerial duel success rate was 80 per cent and 56.1 per cent respectively. However, since moving to Celtic these values have fallen to 58.5 per cent and 50 per cent.

I think it is clear Starfelt has not yet fully adapted to life in Scotland but I do expect his performances and these numbers to improve the more he plays in the new system.

After a good showing against Rangers at Ibrox and away to AZ (excluding the own goal) I think there is cause for optimism that Starfelt will come good.

Liel Abada has impressed since arriving

Liel Abada

Abada, at only 19, is an exceptional talent for his age and was a shrewd piece of recruitment by Celtic.

I was concerned initially as, based on data, he showed good output in terms of goals but didn’t appear to be involved with overall play a lot.

I think this has shown in games against strong opposition, such as the Glasgow derby and the second leg against AZ, when he struggled to impact games but he is so young and will only improve to a point where he will impact these games more consistently.

In games where Celtic are dominant, he gets on the ball much more and is always looking to get a shot away or drive at defenders. These attacking traits have led him to be an early fan favourite in Postecoglou's reign.

Abada has provided a constant goal and creative threat in every game this season with 0.41xG and 0.48xA per 90 minutes. If he continues that all season, he could even be a contender to be the league’s top scorer.

With four goals and two assists already to his name, I think Abada has a strong chance of hitting double figures in both statistical categories this season, which would be exceptional for such a young talent in his first season in a new league.
