Leicester City's Claude Puel and Fleetwood Town's Uwe Rosler each expressed reservations about a video assistant referee (VAR) after the technology was used to award a goal for the first time in British football in the teams' FA Cup replay on Tuesday.
Kelechi Iheanacho scored in each half of Leicester' 2-0 win, but it was his strike 13 minutes from time that required the intervention. Referee Jonathan Moss asked to check if the striker was offside before finishing off Riyad Mahrez's reverse pass.
Replays showed Iheanacho was onside when the ball was played and the goal stood as Leicester progressed to a fourth-round tie away at Peterborough.
"I think we saw in the situation that it was important," said Puel, Leicester's manager. "It was a good thing for us. The video is not perfect because we should have had free kicks for fouls on [Vicente] Iborra, but for the goal, it was good."
Rosler, Puel's counterpart, was more suspicious of the decision to allow the goal.
"For me, can they really say he is onside for the second goal or are they guessing?" he said. "VAR is not 100 percent clear because we still don't see everything. But we will see how it goes. There will be problems in the beginning before we get used to it."
Iheanacho has found first-team opportunities limited this season but Puel was pleased to see the £25 million summer signing from Manchester City play well.
"The first half was tough for the team because we played against a strong defensive unit and couldn't find the solution," Puel said. "But in the second half, we played quicker and moved the defenders around a bit more and it was a good goal in the first half.
"I was happy with his game and he showed a good attitude, worked hard for his teammates and got between the lines. His first goal showed a lot of quality and the second was a fantastic move between him and Riyad. It was a good reward for him and the team."
The opening goal after 43 minutes was not only Leicester's first shot on target of the evening but the Premier League club's first of the tie -- including the goalless draw at Highbury on Jan. 6.
"If you break the tie down then I think we were the better team in three of the four halves played, but in the final one they had too much for us," Rosler said. "They are a Premier League team and you could see that in the end."
