Free agent Paul Caddis is rumoured to be training with Pompey this week, with a view to a potential move to Fratton Park.
But what do we know about the 28-year-old right-back who departed Birmingham City last month by mutual consent?
Dan Lewis has collated 10 facts on the Scotland international.
1) A graduate of Celtic’s Academy system, Caddis played on 17 occasions for the Scottish giants – making his home debut in a 3-2 Champions League defeat to Barcelona in 2008.
2) A loan spell at Dundee United followed before Caddis and future Pompey midfielder Simon Ferry were signed together for an undisclosed fee by League One Swindon Town in 2010.
3) Relegation ensued but Caddis stayed at the County Ground and was rewarded with the captain’s armband as he skippered the Robins to the League Two title in 2012 – also being named in the League Two team of the year.
4) A loan switch to Championship side Birmingham followed, with the Blues spending £150,000 on him in 2013 after impressing in his initial temporary stay.
5) A regular penalty taker, Caddis has found the net 13 times in his career, missing just twice.
6) His goal instinct made him a fans’ favourite at Brimingham when his final-day stoppage-time equaliser in the 2-2 draw with Bolton kept the club in the Championship in extraordinary circumstances.
7) Caddis has won one cap for his country, which arrived less than a year ago as a late substitute in Scotland’s 1-0 friendly win over Czech Republic in March 2016 - he has also played for the Scotland’s under-19 team and won 13 caps for the under-21s.
8) His contract with Birmingham was cancelled by mutual consent in late January after falling out of favour under new boss Gianfranco Zola.
9) Caddis has played just once this season in a campaign disrupted by a dislocated shoulder and spent time training with fellow Championship outfit Blackburn recently, although a deal failed to materialise.
10) Mr Versatile, Caddis plays predominantly as a right back but due to his attacking nature, and having two good feet, he can also play at left back and anywhere across the midfield.
