FORMER Celtic defender Mark Wilson thinks that Kieran Tierney could be tempted to leave Celtic to join an English Premier League side in a big-money move. Wilson said: "As much as Kieran Tierney loves playing for Celtic, and has a great relationship with the fans, I’ve no doubts there will be a part of him that wants to go to the top level."

And Wilson has warned Celtic chief executive Peter Lawwell that he will face a furious backlash from irate supporters this summer if the Parkhead club fails to invest heavily in new players. "If Celtic go on to win this eighth title – which is looking likely – then you are talking about the nine-in-a-row year," said Wilson. "Peter and the club will need to throw a good bit of money at this because Celtic can’t afford to fail."

Rangers midfielder Andy Halliday was pleased Rangers were able to salvage their Scottish Cup dreams on Sunday as they came from behind to earn a replay with Aberdeen. Halliday said: "I am happy that we managed to get the job done in terms of staying in the cup and it is just up to myself to keep doing what I am doing and try and force myself into the team."

The Ibrox club's assistant manager Gary McAllister hopes Joe Worrall can add more goals to his game after hitting a crucial equaliser in the draw with Aberdeen on Sunday. "He has been a particular stand-out in the last three or four games," said McAllister.

Ex-Rangers midfielder Alex Rae believes that Steven Gerrard's side could still go on to lift the Premiership title in May. Rae said: "I think there is an outside chance. You have got an Old Firm game coming up at the end of this month."

Rae has also spoken at length about the benefits he received after seeing a sports psychologist to help with the disciplinary probloems he faced during his career. "I realised I needed to get on top of that. I had more control over the way I was behaving," Rae revealed.

And Rae has claimed that hooliganism in Scottish football is now as bad as it was in the days of the notorious casuals back in the 1980s and has called on troublemakers to be banned for life and jailed. "We are at the stage where we need to address it and I would take a zero tolerance approach," Rae said.

Ajax have become the first club to knock Real Madrid out of the Champions League in three years after a sensational performance at the Bernabeu. The Dutch side produced a stunning 4-1 victory to book their place in the last eight of the competition.

Hearts striker Steven Naismith could miss the rest of the season through injury after being taken off at half-time against Celtic last week with a knee problem. The Scotland internationalist has been sent to England to get a scan that will reveal the full extent of the injury.

Aberdeen defender Max Lowe reckons his side silenced the snipers after insisting they outplayed Rangers at Pittodrie. "I think we showed everyone that we can play at home after those question marks over our performances here," said Lowe. "That was real Aberdeen display."

Former Aberdeen defender Russell Anderson has said that he understands the position that captain Graeme Shinnie finds himself in but hopes the midfielder will extend his stay at Pittodrie. Anderson said: "It’s a difficult one for him but he is at a stage now in his career where he needs to make what he feels is the right decision because football can change very quickly and I’ve seen that myself."

Hibernian full-back Lewis Stevenson has admitted that his team will have to improve their quality in attack ahead of Friday’s visit of Rangers. "Especially at home, we think we can compete, we don’t want to just roll over when the Old Firm come," Stevenson said.

Partick Thistle's Christie Elliot, who scored his side's equaliser against Hearts in the Scottish Cup quarter final to force a replay, says he already has one eye on the semi-finals of the Cup. Elliot said: "It is a game (the semi-final against Inverness) we know we can win but obviously we have to put the Hearts replay first and foremost. They are a brilliant team."

Inverness manager John Robertson has joked that he expects to be carpeted by the Scottish FA after channelling Neil Lennon’s famous ‘aeroplane’ celebration against Dundee United. "I lost it for a moment there, it was a little bit of the Neil Lennon aeroplane!" laughed Robertson. "I’ll be expecting a three-match ban from the SFA for that."

Scotland women's assistant manager Andy Thomson believes the squad have already achieved their Algarve Cup aims ahead of today’s third and final match against Denmark. "The most important thing is looking after the players because it’s difficult to recover in two days," Thomson insisted.

In rugby, Scotland duo Sean Maitland and Chris Harris will miss this weekend's Six Nations clash with Grand Slam-chasing Wales after being ruled out with injury.

But Scotland flanker Hamish Watson says that his team-mates are capable of defeating Wales and revealed that his team-mates can inspire themselves to victory. "There’s pressure from fans, maybe a bit from the media, but we’re the ones who put pressure on ourselves to win," said Watson.

And in golf, Ross Kellett has revealed that giving up the sport in search of a more secure 9-to-5 job was one of the best decisions he ever made. Kellett said: "I have a steady income now and can do things I maybe couldn’t have before as golf was holding me back in a sense."

Elsewhere, Simon Ferry has told the Scottish Sun that he believes Rangers will try to sign Aberdeen pair Scott McKenna and Graeme Shinnie this summer.

The Daily Record are reporting that Rangers are tracking Milwall right-back Mahlon Romeo, who is out of contract in the summer.

And Christophe Berra has told the Scotsman that Hearts can take nothing for granted ahead of their Scottish Cup quarter final replay against Partick Thistle next week.
