Celtic are set to sign Paderborn midfielder Mika Baur, with the 22-year-old expected to finalise his £6.8million move to Lennoxtown. The Hoops will also advance their interest in Hajduk Split’s Niko Sigur, while West Ham United remain in hot pursuit of Arne Engels. Chelsea left-back Landon Emenalo is also in Glasgow, having done his medical yesterday and is expected to join on a season-long loan. Winger Haissem Hassan checked in last night from Real Oviedo. Meanwhile, Rangers aim to deliver Derek McInnes a left-back before their weekend Premier Sports Cup clash with St Mirren. The Ibrox recruitment team has narrowed its search, with AEK Athens’ James Penrice and Southampton’s Jayden Meghoma being two of the options. They are working on various options and are expected to push the button on one over the next 24 hours. Rangers have had to move after Tuur Rommens suffered an injury at the weekend, which will keep him out for four to eight weeks. Penrice is the preferred option if they can agree a loan, although AEK’s initial preference was to sell. Talks with AEK are ongoing. Meghoma was previously at Rangers last season on loan.
