The two players, as well as goalkeeper Matz Selz, arrived at Newcastle United this week.
Newcastle manager Rafael Benitez
Goalkeeper Selz became Newcastle’s first signing of the summer transfer window as he joined from Gent on Wednesday.
Gayle and Ritchie joined him at the club on Friday, as they completed moves from Crystal Palace and Bournemouth respectively in what was a busy week for manager Rafa Benitez.
He is expected to be busy in the summer transfer window as he builds his squad for the upcoming season in the Championship.
He is clearly keen to get his signings done early, with all three signings having been secured despite the transfer window being officially open for just one day.
Saturday saw the club start their pre-season schedule, and the three new recruits have been pictured getting to work with their new teammates.
It now remains to be seen how all three signings will fare as the Magpies look to secure an instant return to the Premier League next season.
Gayle and Ritchie in particular shouldn’t find the Championship too difficult, having both flourished in the division in years past.
