Football Insider analyses three talking points from Celtic’s 4-0 win over Hearts in the Scottish Premiership at Parkhead.

New right-back is crucial

It’s just not happened for Cristian Gamboa. A £1million signing from Premier League side West Brom in the summer, Costa Rica international Gamboa has struggled to have an impact since his move to Glasgow and it was apparent against Hearts. Gamboa failed to provide an attacking outlet on the right that manager Brendan Rodgers desperately wants his full-backs to become. Compare the 27-year-old with a player eight years his junior – Kieran Tierney showed Gamboa just how it should be done on the left. A new right-back should be a priority for Rodgers, with two days remaining in the January transfer window.

Like a new signing

Dedryck Boyata’s return to the side has been like a new signing to Rodgers, as he continues to shine at the heart of the Hoops defence. The Belgium international has struggled with injury since Rodgers’ took over from Ronny Deila in the summer, but has since come back into the side to star in the Bhoys side. Now making three appearances since returning, Boyata has kept three clean sheets and is slowly starting to remind fans and staff alike of his talent.

Rodgers should offer teen a pay rise

Kieran Tierney has continued to show why he is one of the best teenagers in Scottish football right now. Two wonderful assists from the attacking full-back almost single handedly earned the Hoops a 3-0 win, as he supplied Scott Sinclair and Patrick Roberts to find the net. The Mirror claimed earlier this month that Man United, Arsenal, Chelsea and Man City all want to sign Tierney, but Rodgers should deter them by offering him a bumper pay rise despite his current deal set to end in 2021.

In other Celtic news, Leicester have targeted 25-year-old star as one part of three-man shortlist.
