The publication claims that Spurs’ emerging interest has come as a “surprise”, but it cannot be ruled out.Speaking to Football Insider, Paul O’Rourke said: “It’s going to be hard for Celtic to keep hold of him this summer, despite rejecting an offer for him in January.“Obviously, they’ve got more time to plan ahead in this summer transfer window. I’m sure Engels himself would be interested in the move away if a move to the Premier League comes up.“For Tottenham, again, their interest has come as a surprise maybe in some respects. They’ve bolstered their midfield already with Sandro Tonali and Mateus Fernandes.“So whether they see Engels joining that as well remains to be seen, but they are showing no signs of slowing down in the transfer market.”Arne Engels continues to attract Premier League interestEngels is a central midfielder capable of playing both as a defensive midfielder and on the right wing.
