Steve Cotterill believes Christian Dailly will invigorate Pompey’s dressing room.
Dailly sealed a weekend arrival with the Blues on a month’s contract after leaving Charlton.
He came off the bench at Middlesbrough to play a role in Luke Varney’s injury-time equaliser.
It was Dailly’s shot which was blocked and fell into the path of Varney, who made no mistake to earn a 2-2 draw.
Cotterill feels the veteran will have a big influence around the club.
And he reckons his presence will keep other players on their toes.
Despite inking a short-term agreement the Pompey boss reckons there’s every chance he could be around for the whole campaign.
Cotterill said: ‘Christian’s not the youngest, we know that.
‘But he’s on a monthly contract and he was able to come on at Middlesbrough.
‘We’ll wait and see how he goes but if we end up having Christian around for a year there would be no problems in having him around.
‘You could see why he’s still out there playing at 37.
‘He may not be as quick as he was but he’s as fit as they come,
‘I’m pleased with him and he’s an influence around the dressing room.
‘And maybe he might just keep one or two others on their toes.
‘He plays games. He’s a proper professional.’
Cotterill was also full of praise for the other new face to come off the bench as Ryan Williams made his senior debut.
Williams, 20 years Dailly’s junior at 17, was introduced on the right flank as Pompey chased an equaliser.
He refused to be overawed by the occasion and made some useful interventions.
Cotterill was delighted with how he stepped up after only coming into the squad in pre-season.
He said: ‘I was chuffed for Ryan. It was nice to be able to put him on. It was nice to do it. It’s great for him.
‘There might have been a few eyebrows raised at taking off experienced pros for a 17-year-old.
‘Well, I’m pleased it worked out. I didn’t know if it would. I didn’t know until I put him out there.
‘He did all right, though. He’ll be a player for us, for sure.’
