Celtic have made two attacking signings so far this window and are continuing their quest to build a Champions League-ready squad06:00, 08 Aug 2026Celtic have signed the fewest players in the Scottish Premiership so far this summer. But Martin O'Neill has championed "quality over quantity."‌It was Camilo Duran who became the first to enter the gates of Parkhead, signing a five-year deal from Qarabag for around £6million. Next up was long-term target Kasper Hogh, who broke the club's transfer record when he arrived for £11m.‌The former Bodo/Glimt striker penned a four-year contract with the option of a further year. This duo scored a combined 10 goals in the Champions League last season. But fans will not be satisfied with these two signings to end the window, especially if they are to lose key players.‌Arne Engels has been heavily linked with a move to West Ham, with the Hoops bracing themselves for a third bid from the Championship side.

Latest news, analysis and much more on Mirror Football's Facebook page‌£17m duo signsThe main transfer target for Celtic is Real Oviedo's Haissem Hassan. The Egyptian winger impressed at the World Cup, assisting once and running the show for a period against Argentina.Oviedo-based newspaper La Nuevo Espana claims that Celtic are pushing forward for the 24-year-old with a move to Parkhead now extremely likely. Sky Sports reports that an initial bid of £6m has been submitted and it could rise to around £9m if all bonuses are met.‌Frosinone's Fares Ghedjemis is the other star Celtic are interested in - although they may have to compete with bitter rivals Rangers for the 23-year-old. The Hoops had been keen on the Algeria international in January but were unable to get a deal over the line.Now, they have reignited this interest and Frosinone reportedly want at least £8m for his signature. It is understood that the Italian outfit rejected a bid of a similar price from the Gers, who have since moved on to target Celta Vigo winger Couhaib Driouech.‌Celtic could now swoop in and stump up the cash for Ghedjemis. This would represent a dreamy £17m outlay for both players, but fans would see this as a reasonable price to pay ahead of their Champions League qualifying match-up with LASK.World Cup star stays putAlistair Johnston has been attracting considerable interest following his impressive performances for Canada at the World Cup. He started every game for the host nation and reached the round of 16, where he was eliminated 3-0 by Morocco.Throughout his Celtic career, the right-back has 21 goal contributions and is beloved by the fanbase for his tough-tackling and positive attitude. Yet Everton have registered an interest in the 27-year-old, with O'Neill confirming that manager David Moyes contacted him regarding Johnston.‌He said: "In fairness, David Moyes did call me last week and say that there would be contact. But I don't know how far that has progressed, if it has at all."But yeah, that would be disappointing obviously. But I suppose it's to be expected, you know, players who have done well. Our job is to try and do our best to keep them. If that's not possible, naturally, we'll have to try and get replacements in. To replace those players would be a difficult task."‌It seems like O'Neill has kept to his word for the time being as the Toffees' interest in the right-back has cooled off. The Daily Record has confirmed that the Premier League side are working on other options after failing to meet Celtic's £15m asking price. If the club want to end the window in style, keeping Johnston is a must.Defensive reinforcements arriveShould Celtic retain Johnston, they may opt to add to their defensive line with another loan move for Brentford's Benjamin Arthur. The 20-year-old arrived at Parkhead last season under the same circumstances, spending the second half of the campaign in Glasgow.Article continues belowReports claim that the Hoops have already seen a bid from rejected, with Arthur part of the Bees' long-term plans. The defender only made four appearances in the 2025/26 season, but this was clearly enough to impress O'Neill.A loan move could be beneficial for all parties, giving Arthur some European experience and allowing Celtic's defensive line to relax knowing they have back-up waiting in the wings.
