Sir Rod Stewart has urged Celtic to raid Dundee of Luke McCowan this summer as he confessed Tony Docherty's side "could be a problem" this weekend.

After reaching the Scottish Cup final with a penalty shoot-out win over Aberdeen last weekend, it's back to league duty for Brendan Rodgers' side on Sunday when they travel to Dens Park for the first of their post-split fixtures. The Hoops go into the split with a three-point advantage over Rangers at the top of the Scottish Premiership but Celtic diehard Stewart is taking nothing for granted going into the final run-in.

Speaking to Alan Brazil on talkSPORT, a hesitant Stewart offered his take on the clash with Dundee - before advising the Celtic Park chiefs to make a move for 26-year-old McCowan. The rocker said: "We can't take our foot off the pedal that's the thing. Dundee could be a problem. Have you seen this young kid McCowan? He plays for Dundee. Wow. He is superb, I hope Celtic have got their eye on him."

And Stewart admitted he felt sympathy for Aberdeen after the Parkhead side saw off Peter Leven's men in a semi-final thriller at Hampden. Despite a penalty shoot-out victory, he said: "They (Aberdeen) were outstanding.

"I actually felt a bit sorry for the Aberdeen supporters, they deserved a little bit more than that. If they can keep that up next year then they are going to be a top-four team, they were brilliant."
