Doncaster sign Grehan and Ajayi

Doncaster Rovers have signed Crystal Palace defender Sean Grehan for an undisclosed fee and taken Tottenham forward Damola Ajayi on a season-long loan.

Grehan has agreed a three-year deal with the League One club after making seven appearances for Palace's Under-21s in the EFL Trophy.

"I think it's the right move for me now. I've had a few loan spells and I just want to somewhere, settle in and play games," the 21-year-old said.

Ajayi, 19, scored on his competitive debut for Spurs against Elfsborg in the Europa League last season.

"This is a top club that has just had a great season and I'm ready to kick on," he told the club website.

"I feel like I can see what Rovers are trying to build and I feel like they're heading in the right direction.
