The two new arrivals from Bayer Leverkusen have had fitness issues whereas the Hungarian has hit the ground running this seasonLiverpool made a succession of significant signings during the most sensational transfer window in the club's history. The summer-long pursuit of Alexander Isak obviously dominated the headlines, given the saga was only concluded on deadline day, but the acquisition of Florian Wirtz was the deal that nobody saw coming.The common consensus was that if Bayer Leverkusen were to actually sanction the sale of their most prized possession, he would go to Bayern Munich or Manchester City. However, Liverpool suddenly and surprisingly emerged as the frontrunners in the race to sign Wirtz at the start of June before agreeing to pay an initial £100 million (£135m) for the attacking midfielder.The news understandably sparked mass excitement around Anfield. Fenway Sports Group (FSG) had finally decided to splash the cash - and one of the finest young players in world football was on his way to Liverpool.Amid all of the hype and hysteria, Dominik Szoboszlai was largely forgotten. The Hungarian had played a pivotal part in last season's title triumph yet the presumption was that he'd simply accept a supporting role in Arne Slot's squad.Szoboszlai, though, has been Liverpool's star performer during the first three rounds of the new Premier League season - and even with Isak now on board, there's no reason to think that he'll suddenly be relegated to the bench.On the contrary, Szoboszlai has arguably made himself un-droppable - because he's not just posing a threat to Wirtz's status as a starter, he's also emerged as an attractive alternative to another summer signing from Leverkusen, Jeremie Frimpong, at right-back.
