PARIS: Big-spending Paris Saint-Germain might sign a holding midfielder during the winter transfer window as they pursue their dream of winning the Champions League, coach Unai Emery suggested Monday.

Qatar-backed PSG sent shockwaves through world football by luring Brazilian superstar Neymar from Barcelona for 222 million euros ($261 million) and setting up a record 180 million euros deal for teenage sensation Kylian Mbappe.

But the impressive riches of their forward line are not yet reflected in their midfield.

“Thiago Motta is a sentry for us and when he's out we don't really have a replacement,” Emery told a press conference on Monday.

His side have a are runaway leaders in France's Ligue 1, but face Cristiano Ronaldo-led Real Madrid in a keenly-awaited Champions League last-16 double header in February.
