Celtic and Rangers are both pushing to strengthen their attacking options this window, with reports suggesting both Glasgow clubs are closing in on new wide players from European clubs.
Celtic have reportedly tabled an offer worth around 11 million euros, roughly £9m, for Real Oviedo's Egyptian winger Haissem Hassan, 24. According to reports out of Spain, Oviedo are expected to accept the proposal from the Scottish champions, with only minor details still to be ironed out before the transfer can be finalised. Spanish outlet La Nueva Espana has indicated that Oviedo are already working through the final stages of Hassan's exit from the club.
Should the move go through, Hassan would become the latest attacking reinforcement to arrive at Celtic Park as the club looks to bolster its squad depth ahead of the coming campaign. However, sources suggest Celtic's business is not expected to stop there, with the club still said to be actively looking at the market for both a new goalkeeper and a left-back as they aim to address other areas of the squad.
Across the city, Rangers are also in the hunt for a new winger, having lodged a bid worth £6m for PSV Eindhoven's Couhaib Driouech, 24. The Dutch club and Rangers are understood to be in discussions in an effort to reach an agreement over a transfer fee, though it remains unclear whether that has yet been finalised.
Personal terms with the player himself have not yet been agreed, though reports suggest Driouech is open to a move to Ibrox should the two clubs settle on a fee. That said, Rangers may face stiff competition for his signature, with Spanish club Celta Vigo reported to be confident of winning the race for the winger ahead of the Scottish side.
The interest from Celta Vigo could complicate Rangers' pursuit, and it remains to be seen whether the Ibrox club will be able to convince both PSV and the player himself that a move to Scotland is the right step, particularly with a La Liga club also showing strong interest.
For Celtic, the pursuit of Hassan appears to be progressing more smoothly, with the Egyptian international seemingly close to completing a switch that would see him swap Spanish football for Scotland. His arrival would add further competition and quality to Celtic's wide attacking options as they continue to build their squad under the current transfer strategy.
Both clubs remain active in the market as the transfer window progresses, with the two Old Firm rivals continuing to look beyond domestic borders for fresh talent. While Celtic's move for Hassan looks close to being wrapped up, Rangers' pursuit of Driouech appears more uncertain given the reported competition from Celta Vigo.
Neither club has yet confirmed the deals, and further details are expected to emerge as negotiations continue between the clubs, agents and the players involved. The situation remains fluid, particularly regarding Rangers' target, with the Ibrox club needing to move quickly if they are to fend off interest from Spain.
As the window continues, attention will remain on both Glasgow clubs as they look to finalise their business and strengthen their squads ahead of the new season, with wingers clearly a priority for both sides of the Old Firm divide this summer.
