Tottenham have completed the £11m signing of midfielder Victor Wanyama from Southampton on a five-year deal.
The move will see him reunited with Tottenham boss Mauricio Pochettino, who managed the 24-year-old Kenya captain during his spell as Saints manager.
Wanyama arrived at St Mary’s from Celtic for £12.5m in 2013 and scored four goals in 85 Premier League games.
He asked to leave last summer after interest from Spurs but stayed, helping Southampton to a sixth-place finish.
In a letter addressed to Southampton fans published on his website, Wanyama wrote: “It is very emotional for me to say goodbye to the club that gave me the chance to be the first Kenyan to play in Premier League.”
He added: “I will never forget my time in Southampton Football Club, I will keep club forever in my heart.”
The signing is Spurs’ first since they finished third in the Premier League to secure a place in the 2016-17 Champions League group stages.
He moved to Scotland from Belgian club Germinal Beerschot for an undisclosed fee in July 2011, having initially joined Helsingborgs of Sweden in 2007.
Chris Coleman’s Wales side qualified for the last 16 as Group B winners – ahead of England – while Michael O’Neill guided Northern Ireland to third place in Group C.
They are in the opposite side of the draw to England, current world champions Germany, reigning European champions Spain, four-time World Cup winners Italy and hosts France.
“Obviously you come to the tournament for one reason – to win, not to play three games and go home,” said Bale, who is Euro 2016’s joint top-scorer with three goals in the group stage.
“The ultimate goal is we want to try and win the tournament.
“It’s a cliche but we’ll take each one as it comes. Yes, we would love to win it, but all our focus now is on Northern Ireland.”
Lafferty, who is yet to score at the tournament, said: “We honestly believe with our heart and determination that we can beat anyone.
“With the squad we have I honestly am sitting here thinking we can go all the way. If we get a bit of luck we can upset a few teams.
“It’ll be interesting to see who it wants it most on Saturday. I believe we’ll come out on top.”
‘Similar team spirit’
Prior to their defeat by England in the group stage, Bale suggested Wales had “more passion and pride” than Roy Hodgson’s side – and the two-times Champions League winner thinks his team have more in common with Saturday’s opponents.
“They topped their [qualifying] group, you don’t do that by mistake,” said Bale.
“They have very similar team spirit to us. They are a bit more defensive than us -it will be difficult to break them down, but we will try our best.”
Meanwhile, veteran Northern Ireland defender Aaron Hughes, 36, expects the supporters of both teams to make the match a memorable occasion.
“It’ll be a fantastic game,” the 102-capped player said. “I think the atmosphere will be tremendous – as good as any here.
“Everyone has seen how good our fans have been so far and the Wales fans have been similar. One of the best atmospheres I played at was against Wales at the Millennium Stadium in 2004.”
