Manchester United boss Jose Mourinho has reportedly stepped up his efforts to sign Ajax striker Justin Kluivert.

Last month, United were linked with a move for the young Dutchman, who has just 18 months remaining on his contract at the Eredivisie outfit.

According to Sport, Mourinho remains keen on bringing Kluivert to Old Trafford but does not want to complete a deal until the summer.

While the 18-year-old could benefit from regular first-team football with his current team, Mourinho is aware that he could potentially sign the player for a lower fee during the summer.

Kluivert - who is the son of Dutch legend Patrick Kluivert - has netted seven goals in 34 appearances in all competitions for Ajax.
