Pompey have signed midfielder Anton Walkes in a loan deal from Tottenham until the end of the season.
The 20-year-old – who is also comfortable playing at the back – played for Major League Soccer side Atlanta United during the 2017 campaign.
Blues boss Kenny Jackett said: “He can play in midfield, the centre of defence or at right-back and he’s an athletic player, so we’re pleased to add him for the rest of the season.
"He’s someone I have a lot of time for and think he’s got a very bright future."
“The experience of coming to a club like Pompey will be a good one for him and he’ll be keen to help us move towards the top six.
“He’s someone I have a lot of time for and think he’s got a very bright future. He’s certainly got all the tools to succeed.”
Walkes is a graduate of Tottenham’s academy, who made his senior debut from the bench in a League Cup victory over Gillingham in September 2016.
