London rivals Chelsea and Arsenal are reportedly among several clubs keeping tabs on Crystal Palace midfielder Michael Olise.
The 20-year-old was a standout performer in the Championship last season with Reading, contributing to 19 goals in 46 league appearances.
Olise's impressive form in the second tier earned him an £8m transfer to Crystal Palace last summer, and the youngster has settled in nicely at Selhurst Park, scoring four goals and providing seven assists in 21 appearances across all competitions this term.
According to The Sun, Chelsea, Arsenal, Everton, Bayern Munich and Lille are all closely monitoring Olise's development at Palace ahead of a potential move for the midfielder in the future.
Patrick Vieira is, however, desperate to keep hold of the France Under-18 international, who is under contract at Selhurst Park until June 2026.
Olise has featured predominantly on the right wing for Palace this season, but for Reading the youngster also operated on the left flank and in an attacking-midfield role.
