Newcastle United's new Saudi ownership made a significant move by signing Brazil midfielder Bruno Guimaraes from French club Lyon for 50.1 million euros ($55.8 million) and 20% of any future sell-on value.

Lyon announced the transfer fee on its website and Newcastle tweeted that he signed a 4 1/2-year deal. The Saudi sovereign wealth fund bought Newcastle in October and the Premier League club tweeted “Bruno is a Geordie.” The club also showed a photo of him signing his contract.

Guimar?es was not first-choice last season after joining from Athletico Paranaense two years ago for 20 million euros ($22.3 million).

Last year he helped Brazil win the Olympic gold medal at the Tokyo Games. Overall, he scored three goals in 71 games for Lyon.?
