Transfer rumour roundup: Liverpool accelerate centre-back hunt; Man United want £40m for Onana

Today's transfer rumours feature Manchester United 's asking price for Andre Onana and Liverpool 's centre-back search.

Andre Onana has become a forgotten figure at Manchester United . The Cameroonian's calamities have faded in the memory amid Senne Lammens' cool head in goal, with Onana currently farmed out on loan to Trabzonspor .

Hopes of a permanent deal look to have been dashed, however, with the Turkish team unwilling to meet Onana's asking price. The Manchester Evening News claim that United want a whopping £40m for the goalkeeper, as the club look to recoup their investment.

Liverpool's search for a centre-back is accelerating. Fichajes report that the Reds are 'firming up' interest in Nottingham Forest 's Murillo , in a deal that could cost £70m. It comes as Ibrahima Konate edges closer to the Anfield exit, with the Frenchman back on Real Madrid 's radar after an upturn in form. Konate's contract expires in the summer.

It looks likely to be a midfield market in the summer, with Adam Wharton, Elliot Anderson and Sando Tonali among the big names tipped for transfers . The latter heads Arsenal 's list of potential additions to the engine room, though Tuttosport tell us that the Gunners face competition from both Manchester clubs.

City, however, also like the look of Felix Nmecha, say Football Insider. The Borussia Dortmund midfielder is one of a collection of ex-City academy alumni to have thrived since leaving the Etihad.

Meanwhile, City stars are on the agenda for Spain's big two. Barcelona want Nathan Ake in a cut-price deal after the Dutch defender's fall from favour this season, while Real Madrid continue to chase Rodri.

According to Defensa Central, president Florentino Perez is ready to rip up the rule book to sign the Spaniard. Los Blancos usually have a rule of not spending more than €40M on players approaching 30.
