Scotland vs. England: Who to Watch in Tuesday's Friendly Matchup

Scotland and England resume the oldest rivalry in international football at Celtic Park on Tuesday night, with players on both sides looking to shine in a match that's shaping up to be a friendly in name only. Both teams come into this game on a high after Euro 2016 qualifying wins, and their clash is sure to produce a heated affair.

According to Henry Winter of The Telegraph, Roy Hodgson is set to make some changes to the England side that beat Slovenia 3-1 at Wembley, while Gordon Waddell of the Daily Record reports that Hodgson's counterpart Gordon Strachan is expected to do the same, with both managers opting to mix youth with experience.

Here are four players to watch in the Scotland vs. England match.

England: Saido Berahino

The 21-year-old striker is in line to start in Glasgow and will be looking to grab a goal on his senior debut after scoring an impressive 10 goals in just 13 under-21 appearances for England.

The West Bromwich Albion forward is the highest-scoring Englishman in the Premier League this season—netting seven goals in 11 games—and has already surpassed his league total from the entirety of last year. 

Berahino has been in imperious form of late and will look to not only take chances, but create them as well, having laid on eight goal-scoring opportunities for his team-mates in the Premier League. 

Although he was an unused substitute against Slovenia, the Burundi-born Berahino is clearly delighted to be part of the senior setup.

However, he will need to be disciplined on what is sure to be a physical encounter with the "Auld Enemy."

This is especially important, as he will line up against Baggies team-mate James Morrison. Berahino clashed with Morrison in March after refusing to apologise for an error that cost West Brom a victory against Cardiff, per James Nursey of the Mirror.

England: Fraser Forster

With Joe Hart allowed to return to Manchester City after playing against Slovenia, the door is open for Southampton stopper Fraser Forster to make his third cap for the Three Lions (if he gets the nod ahead of Ben Foster).

According to Matt Law of The Telegraph, Foster has warned his team-mates that Scotland will be looking to "kick lumps" out of them amid a hostile atmosphere at Celtic Park.

Forster, who enjoyed four successful years at Celtic before making the switch to Southampton in the summer, knows just what to expect, per Matt Law of The Telegraph:

"

It's an unbelievable atmosphere at Celtic Park. ... It's a fantastic stadium, it's quite tight, so it will be really loud and will make for a fantastic game.

"

The 26-year-old has been a key part of the Premier League's surprise package Southampton this season. He has helped his team boast the best defensive record in the division, letting in just five goals in 11 games.

Standing at an imposing 6'7", the Saints No. 23 should be well-suited to a physical game with the Scots.

Scotland: Craig Gordon

Fraser Forster's successor at Celtic could make his 41st appearance for Scotland—almost four years to the day since his last cap—after manager Gordon Strachan announced that No. 1 David Marshall, who starred in the Scots' 1-0 win over the Republic of Ireland on Friday, had a "bit of a groin strain," according to Andrew Smith of the Scotsman.

As noted by Gordon Waddell of the Daily Record, a return to the national team for Gordon, who suffered a career-threatening knee injury that kept him out of action for two years, would help the 31-year-old put a difficult spell behind him.

Like Forster, Gordon's efforts in goal this season have contributed to his team's excellent defensive record—conceding only eight goals in 12 SPL matches—and leave Celtic in a strong position to qualify from Group D in the Europa League.

If Gordon can replicate his club form on Tuesday, the Scot could ensure a barren night in front of goal for England's frontmen.

Scotland: Lewis Macleod

Since he earned his first senior national call-up, two Rangers players have been vocal in their support of team-mate Lewis Macleod, describing him as the best young player either has ever seen.

First, Richard Foster told Colin Duncan of the Daily Record, "I have nothing but the highest praise for Lewis. He is exceptional, the best young player I have seen come through at a club."

Rangers defender Darren McGregor spoke to Andrew Dickson of rangers.co.uk, adding, "It's not just his application on the football park. It's his application off the park as well that's impression [sic], and he's a really grounded, nice boy."

According to Scott McDermott of the Daily Record, Macleod has been far and away Rangers' best player this season, as demonstrated by his impressive return of eight goals from midfield.

Humble Macleod, 20, has a good head on his shoulders. This will serve him well in the cauldron-like atmosphere at Parkhead on Tuesday, ensuring he doesn't find himself swept up in the occasion.

Scotland fans will be hoping Macleod can perform a repeat of the wonder goal he scored against Livingston just over a month ago.
