'A lot of dross' - Joe Miller delivers verdict on Celtic recruitment in recent years

By Danny Wright

Joe Miller believes that Celtic have recruited “a lot of dross” in recent years and that they should spend big on trying to bring Patrick Roberts back to Parkhead.

The 20-year-old’s 18-month-long loan spell with the Hoops has come to an end and Miller would love to see his old club strike a permanent deal for the Manchester City attacker – even if it means stumping up a staggering £20million to get him back.

Miller, 49, spent six years with the Bhoys during his playing days and thinks Roberts should be Brendan Rodger’s top summer priority.

“He’s only 20 and has got so much to offer. He’s only going to get better,” said Miller about Roberts, as quoted by the Scottish Sun.

“Celtic have got enough money in the bank and they also know he wouldn’t be a gamble. Spending big money — and I’d even go £15million or £20million — would be well worth it for the lad. Look over the past five or six years, there’s been a lot of dross come into Celtic. Just wasted money.

“They’ve picked up good money and Celtic must have lost millions on them.

“It’s time for the club to say, ‘This boy’s a brilliant talent; let’s keep him and develop him even more.’”

Roberts made 60 appearances across all competitions for Celtic but really came into his own when Rodgers took charge of the Glasgow giants last summer following the departure of Ronny Deila.

The nine-times England Under-20 international has made 47 appearances in both Scottish and European contests this season, scoring 11 goals and supplying 19 assists and Celtic won the domestic treble without a single defeat.

He has only made three first-team appearances for his parent club Man City since signing for them from Fulham in 2015.

Roberts has grown fond of the Hoops during his loan spell and has recently posted a heartfelt goodbye message on his Twitter page.
