Ellis Harrison’s first four appearances for Pompey this season all came from the bench.
But the striker was on the pitch from the start for the last two league games against Burton and MK Dons.
He has certainly made a positive impact, with the Blues winning both fixtures, while he netted the winner from the penalty spot against the latter team last Saturday.
For Harrison, however, seeing his side climbing the League One table is more important than his personal form.
He said: “Whether I’m in the starting 11 or not, we’re winning games and that’s the most important thing for the team.
“You look at the game last week and MK Dons had a lot of possession, but we ended up with the three points and that’s the only stat that counts.
"Whether I’m in the starting 11 or not, we’re winning games and that’s the most important thing for the team."
“We only got two points from the opening three games, but have collected six from the last couple of matches.
“Now we’ve got Doncaster and they play some excellent football, so I’m sure we’ll have to defend well and look to stop them.
“It’s about making sure we get that part of our game right, while also trying to take our chances when they come.
“We’ve had a successful run of fixtures in recent weeks and we want that to continue with three points on Saturday.”
Harrison has been impressed by the start of Michael Jacobs’ Pompey career following the midfielder’s arrival last month.
The 26-year-old said: “He’s got experience and finds those little pockets. He’s a really clever player and it’s a shame the fans can’t be in the ground to see that.
