Liam Walker will be asked to link up with Pompey in England next week as Michael Appleton continues to run the rule over the midfielder.
The 24-year-old played 60 minutes in last night’s 5-1 defeat to Brighton at the Barcelo Montecastillo Resort in Spain.
Playing an advanced midfield role, he impressed with his passing and sent one left-foot shot narrowly over the bar from long range.
That showing and his two training sessions with the Blues have convinced Appleton to have another look.
Now Walker will come to Pompey next week as his trial period is extended.
Appleton said: ‘Liam was fine last night, although, he is obviously worried because he knows he is not fit at the minute.
‘But he has got great feet, a great switch of play and is someone we will look at over the next couple of weeks.
‘There are still three weeks of pre-season so if we can get him over and have a look at him then I’m sure he will be delighted.
‘He’s got ability and the thing I like about him is he is similar to Brian Howard in that I feel you need a mixture in your team and he is left-footed and sees a pass.
‘He will give us something a little bit different to what we maybe have in the middle of the park.’
However, Pompey will not be following up their interest in triallist Julien Lopez.
The French left-sided midfielder appeared in both the Blues’ matches on tour but did not convince.
Gibraltar keeper Jordan Perez, who appeared as a second-half substitute against Brighton, will also not be retained.
