Republic of Ireland boss Heimir Hallgrimsson was unaware of the controversy surrounding Robbie Keane’s visit to the camp but says the former captain’s presence was “a good thing” for his squad.

Ireland’s 44-year-old record caps winner and goalscorer was at the team hotel on Monday night to meet the current players and hand out caps ahead of the Nations League fixtures against Finland and England.

However, Keane’s trip prompted criticism on social media, following his decision to remain in the role of Maccabi Tel Aviv manager amid Israel’s military action. He went on to leave the position in June, after guiding the club to the league title.

Asked about the fall-out, Icelander Hallgrimsson said initially: “I wouldn’t know. I am not the best to answer that.”

When the reason was explained to him, he added: “I didn’t know about it.”

Former Jamaica boss Hallgrimsson did, however, praise Keane’s speech to his players and the words of wisdom a man who won 146 senior caps and scored 68 goals was able to pass on to them.

He said: “He had a good speech. The players were asking him questions. I think it is good to connect past players, the legends from the past to the present.

“What was really good was how he, as a goalscorer, a really high-profile player at his time, was talking about the importance of team unity, fighting for each other, team spirit.

“It was probably not what you would think a striker would say, scoring all his goals, but I think it was a really good message to the players.

“We did the same in Jamaica – brought in old legends just to connect the past and the present. I think it was a good thing.”

Central defender Nathan Collins revealed Keane was able to give the current generation an insight into a different era.

Collins said: “As a kid growing up, these are the players you watch. You watch him every international camp, you watch him score his goals for Ireland.

“You can’t talk to him on a personal level back then, you can just see what he is doing on the pitch, but now you see them on a personal level, what it means to him and what his team did.

“It’s nice to know that we are in a similar boat and what we are building here is what they had as well. We can take a lot of things from what he said and use them in our team.”
