Doncaster Rovers boss Dean Saunders felt his team's first ever win at the Ricoh Arena was a good victory.
Speaking to the Press Association, after the 2-0 victory, Saunders said: "It's a good win for us. I treated it like a normal game. I prepared them as if it was a cup final, like I always do.
"They have gone out and fought like they did at Middlesbrough [0-0 draw on Tuesday] - like they have all season really. We kept the ball out of our net today which gives you a chance of getting a result.
"We should have stayed up. I know it is easy saying it but we have thrown too many games away by missing, missing and missing and then making an error at the other end.
"I am not frustrated because our fate was sealed a long time before this game but I feel a bit sorry for their manager today and the club because I played against Coventry all of my career in the top league.
"Portsmouth are a massive club and Coventry are an even bigger club, arguably, and we have to compete with them next year and it's going to be difficult."
