Manchester City are reportedly exploring a move for Crystal Palace defender Marc Guehi this month.
BBC Sport say they are weighing up whether to make a formal approach for the England defender, who is out of contract at Palace at the end of this season.
It follows injuries suffered by Josko Gvardiol and Ruben Dias in City’s 1-1 draw with Chelsea on Sunday.
The report adds that Liverpool, who failed in an attempt to sign Guehi last summer, as well as Bayern Munich are also keen on the 25-year-old.
City have also recalled youngster Max Alleyne from his loan spell at Watford to ease their defensive injury crisis.
Tottenham are among several clubs interested in RB Leipzig winger Yan Diomande, according to Sky Sports.
It was reported last week that Manchester United are also keen on the 19-year-old, who has impressed in Germany this season.
Liverpool could allow Federico Chiesa to return to Juventus this month, with Fabrizio Romano reporting that the Italian is open to a move back to his former club.
And West Ham have added another striker to their squad by signing Taty Castellanos from Lazio.
